Perfect timing! I was looking for a low power board for my project. Very good presented! Thanks Andreas.
Glad I could help!
As always, as informative and helpful as it can. Congratulations Mr. Spiess
Thank you. Glad you liked the video!
Thanks Andreas. This video's data will help tremendously. Happy Holidays!!
Happy holidays, too!
Many thanks - again - for the high quality content around ESP32! (and have a nice Christmas and a happy new year!)
You are welcome. Happy holidays, too!
Huge thanks for all your excellent videos this year. They have really helped to keep me sane in a challenging year. I don't know how you find the time to make so many informative (and funny) videos.
Hope you have an enjoyable new year. Looking forward to more fun next year.
Thank you and a Happy New Year to you, too!
This video was well made and very informative.
Thank you for making and sharing it.
Glad you enjoyed it!
Thanks for taking the time to update the ESP32 boards and the reminder about shipping costs! Happy Christmas Andreas :)
Thank you and happy holidays, too!
Another great video! Thanks a lot. You put so much work into planning out and making these videos they are so informative. I also love your soft Swiss accent. Thank you.
Glad you like them! And Thank you for your nice words.
A. very thorough and informative video (we wouldnt expect anything less!) Keep up the good work Andreas. The Electromaker team will be looking forward to your videos in 2021 :)
Thank you! I hope I will find some interesting stuff also in the future...
Thank you, this is a really great video full of lots a useful information. Have a wonderful Christmas.
Thank you. And happy holidays, too!
@@AndreasSpiess please can you do a review on an ESP32 with an inter grated camera module and a built in microusb for power
@@Riazbapoo DroneBot Workshop has what you are looking for
Thanks for this video, I have more than 10 ESP boards laying on my desk and always difficult to chose the right one for the right project, your spreadsheet is a very good reference.
Glad I could help! I am glad we have a choice, especially the LoRa boards were very handy for a few projects...
Wonderful videos, keep up the good work! (just found these, love especially all the rf stuff)
There is quite some RF stuff on this channel...
Merry Christmas Sir and have a nice weekend. Thanks for all these great videos
Happy holidays to you, too!
Another great video topic so useful to have real data to help decide which is best. Have a safe and relaxing Christmas period. Simon
Happy holidays, too!
Awesome analysis! Merry Christmas and happy New Year!
Same to you!
Thanks for all work you put into these vids, with lots of useful information. It's interesting to see that only one board use a decent antenna. Cheers
Most Wi-Fi connections are not critical I think because of the small distances.
@@AndreasSpiess Agree, for the hobbyist and many of this channels viewers. One interesting spin to these tests would be, what would the design criteria be for the "ideal" ESP32 maker board, maybe a community challenge you can bring up -- if we can agree ... Lol.
Nice overview ! Very handy. Recently I also found out about the increased shipping costs... So sad !
Happy holidays and the best of whishes for a happy new year ! Thnxs and congratz for all the videos of the past year. Usefull and interesting....
I think we all knew that this will come one day... Also Happy Holidays to your and your family!
ESPectacular work dear Andreas!!! Thanks for your effort!
You are welcome!
This is awesome, thank you Andreas!
My pleasure!
Thank you very much for the another useful video overview.
Glad it was helpful!
Thank you so much! Your videos helped me a lot. Thank you for sharing all the knowledge!
You are welcome!
Thank you. Merry Christmas. 🎄
Happy holidays to you, too!
Great video. Thanks for sharing the comparison sheet!
Not my task. This is why I started the "Superpower" project ;-)
@@AndreasSpiess We need SuperPower board soon - as there are no good choices out there as you pointed out in other video. Happy Holidays!
I wish you a Merry Christmas and a wonderful 2021 to you and your family. Take care and be happy !
Thank you! Happy Holidays to you, too!
I hope you'll have a safe and Merry Christmas. Thank you for all the interaction and your kindness.
You are welcome. Happy New Year to you!

What's her deep sleep current? ;)
A cookie from time to time ;-)
@@AndreasSpiess what is the deep sleep current consumption for this board? www.aliexpress.com/item/33006577783.html
I do not know.
Great video, just what I was looking for!
Glad I could help!
I literally posted a question about the TTGO T-Display myself a few days ago on one of his videos too =)
Gruß di Andreas, thanks for another great video! Frohe Weihnachten und ein guten Rutsch!
Thank you. And Happy Holidays, too!
Thank you Andreas. Very helpful, as usual.
Glad to hear that!
You saved me, what a good video. Thanks a ton!
Glad the video was helpful!
Hi Andreas. Thank you for the comprehensive review. I think it's time for me to get more ESP32s :-)
Only if you have projects in mind. But this should be no problem for you...
Great video as always 👍
Happy holidays to you and your family 👍💖😀
Thank you! Happy holidays to you, too!
so organised and a spreadsheet to match, I had to subscribe
Welcome aboard the channel!
Hi Andreas, thanks to share your knowledge as you do.
You are welcome!
Andreas, thanks for mentioning shipping costs and woes. I have been fighting these lately, as well as items getting lost, cancelled or significantly delayed. I find ordering through distributors and through bigger eBay sellers and Amazon and those with local stock to be faster, more reliable and affordable. Digikey was a favorite distributor when I was a design engineer for similar reasons. As with much of the pandemic I fear these choices may result in smaller businesses being pushed out, but what can you do? +1 for a future video on the topic and the supply chain in general. Thank you.
Thank you for sharing the good info!
My pleasure!
thanks, very clear comparation.
You are welcome!
You r the best Andreas! Tks very much!
You are welcome!
You are the BEST!!! Thank you!

Welcome aboard the channel
(removed... prices already in the list (headbang)) thank you Andreas for this module overview. Mary Xmas and be healthy.
Happy Holidays to you, too!
Happy New Year, Andreas :)
Happy new year to you, too!
Damn! Great video!
Thank you!
Great video! Quick note about the TTGO T7 versions and the Live D1 mini: The inner pin headers have the same form factor and pin layout as the Wemos D1 mini. This enables a lot of readily available shields to be used! They can often be a drop in replacement by just changing some pin definitions.
I always use the TTGO T7 V1.3 as it does not have PSRAM, and thus has pins 16 and 17 also available!
Thank you / bedankt Marc. That was my question. I have a few MH-ET Live and the are really nice but without battery support.
Good point with the small shields. I used them in a project in the past where I build 30 for a IOT introduction...
Great Content 👍
Glad you think so!
Thank you!
You're welcome!
Thanks, nice overview. I love the Lolin D32 v1, lasts very long on battery with deep sleep and it can measure thre battery voltage with an internal voltage divider on GPIO35
Good to know that it already has a voltage divider. I added the info to the spreadsheet
I tried to buy one but they have sold out. I ordered another variant and hope it has the same low Iq ☺
Thanks for this info.Very useful .Could you take a look at the LilyGO TTGO T-Watch-2020 - ESP32.Seems interesting.
Maybe ;-) (I have one laying on my desk)
@Andreas Spiess - I have tested really a lot of ESP32 boards because i do this on a daily work day. I mean use ESP32 boards for profeesional use. I use always now since a year and a half the LOLIN D32 Pro. The one with the display adapter, ssd battery and SD card adapter. VEry well working and coding for use of both cores. I that time the 1 1/2 year i have tested Europe produced boards too because of warranty issues when needed. But still ím on the D32 Pro. It works very well and i use all connectors. Coded is all in C++. Thanks for sharing your view.
Thank you for your feedback! What European boards did you test?
@@AndreasSpiess I will come back to you on discord in your channel via a PM when this is ok for you.
Great info
Thank you!
Now there's a new S3 based TTGO T-Display. Looking forward to a review, with heaps of quality technical detail.
There are a lot of new boards on the market. Maybe I will do such a video in the future...
This is REALLY helpful 👍
Glad you like it!
@@AndreasSpiess Andreas, I'm one of the unfortunate ones who can't program esp32 using their Mac with OS 11.x . If anyone is going to know it is yourself, have you ever come across a solution to this?
I thought the Arduino IDE is MAC compatible. But I do not own one.
@@AndreasSpiess it is - the problem is to do with communication with the usb-serial bridge. And I admire people who refuse to buy anything
Very nice !
Thank you!
Great Video, useful spreadsheet.
Pity about some of the gaps - I'd really like the deep sleep power consumption figures for the MHET Live D1 Mini.
On closer inspection the TTGO T7 V1.4 appears to be pin compatible with the MHET Live D1 Mini, and the TTGO T7 V1.5 is also very similar, and might be able
to be retrofitted to a project with a minor code change/rebuild.
Your channel provides information that really needs a lot of effort to gather from elsewhere,, you deserve a lot of subscribes sir, i always try to let everyone i know to subscribe to your channel because it's not fair..
have a great year Mr. Andreas
Thank you for your support!

Hey Andreas, thanks for the informative video and happy new year. I'm not sure what you mean with "board definition" at 5:15, however I usually put 2.2uF Cap between EN and GND, maybe that fixes your problem? You could just tinker a small "Cap-Jumper" for that adapter board.
You are right with the cap. I got the hint last week and I added it to all my boards.
Thank You
You're welcome
Thanks a lot for the video, I was just looking for a small ESP32 board for my KaRadio and thanks to your video, I found the good candidate. I also didn't know there are boards with battery support, so another problem solved by watching your video :)
BTW: could you also provide links for those battery connectors? I found JST-PH but I am not sure if all of them are 2mm pitch or there are variants. Thanks!
Evening Andreas, Merry Christmas mate from Australia. No gold two weeks ago, but been offered access to farms land.
Thank you. Happy Holidays, too! I hope you new possibilities pay off...
Thanks Andreas this will greatly help users to save their tons of time, I don't know how i missed the previous comparison video or may be i forgot, can you please share the link in the description, thanks
You find them easily with the numbers given in the video.
Hi Andreas, thank you for your work done in 2020. I am wishing you a Merry Xmas and a healthy corona free 2021.

Excellent overview! I'm quite interested in a look at the ESP32-S2 chips and boards. They seem to have more usable I/O pins than the ESP32. (Your recent video about which pins to use on the ESP32 has been invaluable) With ESP-IDF 4.2 finally being released, I'm hopeful the S2 chip will get support in PlatformIO soon. Thanks as always for the interesting content
The Arduino support is essential for this channel. And I also would like the new USB functionality.
Dear Andreas, as allways: a nearly perfect video made in Switzerland (our great little country) and off course a funny outro. Whats the name of your cat? Kind regards, best wishes, wonderful freaking christmas and everything I forgot to wish, delf
Her Name is Dishka.
Happy Holidays to you, too!
Wonderful boards
I agree.
Thank you for sharing your experiances. I really like the swiss dialect as well - in english as well as in german. :-)
As I always had very good experiances with the D1 mini with ESP8266, the D1 mini version of the ESP32 looks interresting to me.
Greetings from the rhine-main-region, germany
Alex
You are welcome!
In my recent video I added a few more boards to the list...
Deep sleep current while USB powered is sometimes also important. For example when building a sensor, that also measures temperature. Deep sleep power usage from the board can easily affect the measured temperature 0.5 - 1 degrees. A lot also depends on proper case design for such a sensor.
I am not so sure if a few microamperes will create a lot of heat. I anyway would not put a temperature sensor near the MCU because it can influence the temperature when it iis active.
The best teacher!
Thank you!
Thank you Andreas for this interesting and informative video.
For me it would be interesting what kind of battery protection these boards do offer. Do you have a video about it?
I'm really carefull when it comes to liPo/LiIon batterys, probably because I don't have enough knowledge about it.
Thanks again and have a nice Sunday!
I added the chips, so you can have a look on the capabilities of them. H have some videos about the topic on the channel.
Thanks for your effort! What's your favorite out of the whole list then?
I think I mentioned it in the video.
Great informative video! Is the lab-cat at the end a reference to the "Metro-Goldwyn-Mayer" lion ;-)?
Nice idea! She seem to have a lot of fans, so she sometimes appears on stage...
very good
Thank you!
Thanks a lot. I was struggling what module does fit the best.
Glad it was helpful.
Thanks for the video! What is your current favorite cheap (Aliexpress) board?
I use several boards according to the needs. There is no "best" board for me.
Great video as always! Looking forward to a video about the new Lilygo esp32s2 board since I recently bought some for a project. Maybe you can figure out how to make it work with PlatformIO?
I am not in a hurry with the S2. So far I do not see a lot of advantages. What was your reason for choosing this chip?
@@AndreasSpiess i have to agree...being only single core.. its quite limited.. its gonna stuggle doing wifi at the same time as anything else (hell the dual core esp32s stuggle in some situations!)..it has less SRAM and ROM aswell..no BLE and no ethernet... but it does have some really, really nice features that i hope they add to the dual-core esp32s... eg upto 128Mb SPIRAM, upto 1Gb Flash, time of flight, 43 GPIOs, OTG USB, LCD and camera interface, and aparently 5uA idle, and 24uA at 1% duty cycle..
Great info here, if you do another of these it would be interesting to the the Tinypico and Tonypico nano by unexpected maker
I have some boards here...
excellent
Thank you!
MERRY CHRISTMAS MY FRIEND! Alton
Thank you. Happy New year to you!
Hi
Nice vídeo as always!
But I believe you forgot one of your initial criteria:
Does the board come with an antenna connector?
On my table it is row I
Cat = instant like. Frohe Weinachten. :)
Vielen Dank. Ich wünsche dir ebenfalls frohe Weihnachten.
Great video as always. Question though why the wemos mini has no deep sleep measurement?
Because it has no battery and for USB a few uA more or less are not important for me.
Oh by the way "MERRY CHRISTMAS " i hope you and the cat are not bloated out on the hams and turkey hope your having a nice day friend tc
This time Christmas was very quiet... Happy New year to you!
@@AndreasSpiess Thank you , alas I was on my own with the cat too. Hope you find happy times very soon.Happy new year p.s you have been a fantastic teacher to us all over the years Andreas here's to many more.

Hello Andrea thanks with this wonderful review. Please do some project or review of ttgo esp32 sim800l.
I decided long time ago to leave 3G modules because the networks are switched off in the next time.
@@AndreasSpiess Yeah you're right Sir. Thanks a lot.
Last picture is the famous CAT display after CRT are no more :) Happy holidays Andreas
Happy Holidays, too. I thought she should be present in the last video of the year. We never know if she is still alive next year...
@@AndreasSpiess Absolutely - I'm sure you give her an extra cookie and she won't decline it :)
I like the ASMR at the end
Maybe I should have done the whole video like that. Less work and more views ;-)
richtig geiles video!
Danke!
Interesting and useful comparison, thanks. Is there a video for the light sensor project you mention at 10:30? A quick search through your past videos didn't find it.
Unfortunately not
Thanks for the quick reply.
@@AndreasSpiess Hello Andreas, maybe you can share with us what board you had selected for charging the battery?
Well maybe the "LIVE D1 mini ESP32" is my favorite because it is small enought for my needs and still big enought to handle. The sd card is still a nice touch for logger/website functionality i think
For the same reasons, most of my projects use a D1 mini or a similar TTGO board with battery interface...
Thank you for this update Andreas, one small feedback, may be call out the board schematic as schematic or schematic diagram, just calling them diagrams is bit confusing.
OK.
@Andreas Spiess excellent videos, they are so helpful. You asked if anyone knows of any ESPs that doesn't need the button pressed to upload code, I have not read the 586 comments below so if this has already been mentioned sorry. The "DevKitc v4" and "ESP32-S2", when uploading code from fast desktop almost never, but with slower laptop most times button needs holding down. So pooling resources with you and others my experience with these modules they have slightly better antennas than the "DOIT" boards, probably because the antennas have more space and over hang the main motherboard. Unfortunately the DevKitc v4 does use the AMS1117 regulator for the 3.3v however the board maker, Espressif, say it is fine to power the 3.3v pin directly with your own power supply, therefore one could assume deep sleep power usage is low but I have not proven if the AMS1117 leaks power on it's output pin, the power LED would also need removing. I power my boards via PoE splitters so I prefer a mix of deep_sleep and light_sleep.
I found a solution to the "button problem". Add a small cap between EN and ground and the problem is gone :-). And yes, the AMS1117 is not made for low current applications.
@@AndreasSpiess That is handy to know, the cap. Keep up the excellent work Andreas.
your videos are also great at 1.25x speed - just a hint for people who love videos ( just at a little higher pace )
Thanks Andreas, I did not know about the ME6211 regulator, might use that in place of the AP2112. It is slightly cheaper with a bit more power. Still using the AMS1117 when it is running a few sensors as well as the ESP32.
The AMS1117 has a very high quiescent current :-(
@@AndreasSpiess Yeah, it is not good for battery power but i am running a vs1053, 2.1W amp, CP2104, IR, RF, LDR, buzzer, WS2812s, a fingerprint sensor, and a nextion on the same board so running with a battery is distant dream :-)
Hello from Indonesia, Uncle Andreas
Thank you for your explanation. It's a very informative and easy understanding video. We also have a project using ESP32-WROOM-32E ECO V3. It is combined with LoRa connectivity inboard. We test it and yeah, the low power & long range is useful.
We are still learning. Hopefully, everyone can give us feedback :).
Once again, thank you for the information
You are welcome! Good lock with your project.
@@AndreasSpiess thank you!
Thank you, this isvery helpful. I still plan to build a Wifi-Weather-Station soon. Most probably I will not use solar but charge the battery, when needed. This would be acceptable for me, if the batteries run for more than a month. I was close to buy a Adafruit HUZZAH32, but after some research this board seems not to be the right choice. I guess the Lolin D32 will be the board of choice.
Have a nice holiday season and stay healthy
Micha
You should be able to reach one month if you do not transmit often and chose the right battery size.
@@AndreasSpiess Thanks, my plan is to transfer every 10 or 15 minutes (if there was a significant change in temp/humidity/air pressure/rain). There will be a short connection to write data to my NAS.
Would you mind to have a look at the tinypico boards? like the pico / pico nano - they are quite awesome regarding size :)
The problem of those boards is the price. I would have to pay 56 dollars for a tinypico and a tinypico nano (18$ shipping included). They are awesome if you need them, I think.
@Andreas. Thanks for your table. I have one question (sorry, I am totally new to this): Is the 3.3V Pin on the boards only input or also output (if powered over usb or lipo), and if yes, how much current does it supply? I am especially interested in the TTGO T7 V1.5. Thanks for an answer.
It is also Output for a few mA
Hello Andreas, first of all thank you for your videos, Merry Christmas to you and your family (cat included). Maybe that sparkfun's high power consumption is due to some unwanted or unexpected current flow path that creates when the microcontroller sleeps? I'm thinking on parasitic diodes on I/O pins or pullup/pulldown resistors which start to dissipate?
Thank you and Happy Holidays, too.
I did not investigate into the power losses. I usually use a "blackbox" approach for such boards.
