- Today we will look at a completely new LoRa board. A new Semtech LoRa chip series (SX1261, SX1262, SX1268) and new ASR6501 microprocessor. Is it the best LoRa board ever? And what about the new LoRa chip? Let’s have a closer look.
The current LoRa chips from Semtech came to the market in 2013. Earlier this year, they finally announced new chips. So far, we did not see them often on the market. Most used boards still are based on the old chips. Recently, Heltec built this new board using one of these new LoRa chips. To find out if this is the best LoRa board ever, we will:
- Compare the new and the old LoRa chips
- Look at this new module used on this Heltec board
- Check if and how good the Arduino IDE supports it
- Measure the output power of the LoRa chip
- Measure the power consumption and check if it really is “low power”
- And finally, you will get my verdict

Thank you, Andreas! I remember asking you for this review exactly a couple of weeks before this. This helps us quite a lot.
TCXO are NOT heated.. They simply have an integrated temperature sensor and compensation circuit that attempts to keep the output stable across a specified temperature band. An OCXO or oven-controlled XO has insulated enclosure and heating element to keep the quartz crystal at the same temperature regardless of external environmental conditions .
You're amaizing. Thank you for your contributions to the world of DIY. You're a blessing to the entire world.
The number of pitfalls that u have prevented me from falling into is amazingly high. So good, on point information, I love it!!!
Hi Andreas! Great video as always. I've read on the TTN forum that Heltec is planning to release a Platformio IDE package and I think this would be really helpful with development. Arduino IDE has some big limitations with external cores still today. I also think they are going to add some documentation since they are still working on it!
Thanks for the information. As a newbe to LoRa, I found your evaluation helpful as I make a decision on what to purchase.
Thank Andreas for all the videos this year!!! I wish you, your family and channel colleges Merry Christmas an excellent 2020!!
Many thanks Andreas. 🎄I wish you a Merry Christmas. 😘
Great video, thanks! Especially the cat at the end purring.
Happy Christmas and a happy new year from London England
Nice explanation again Andreas! I'm amazed how much stuff you know and you also admit what you don't know, that is nice to know! Merry Christmas and happy NEW YEAR for you and your family Andreas!
Thanks for sharing and happy holidays !
Wow! Just what i was looking for ! You are great
Dear Mr Spiess, i wish you a very merry Christmas and a happy new year!
wonderful work Andreas.
Merci Andreas. Interesting product. I wait the library are more stable.
great information. i always wanted to know a few things about lora but still having issue understand it, even after watching a few of your videos of lora... i think i need to find some way to boost some brain cells of mind. thank you
Bit late today getting to this vlog. Good show Andreas have a Happy Christmas and a safe one. That is to your whole family from downunder.
Hi Andreas, another helpful video, thanks. I've been waiting for you to put the OneThinX module which you unpacked 6 months ago through its paces. It was your reference to it which alerted me, and it looks very impressive. I bought one but am still having a few problems with the VSCode tooling so it would be really useful to have a video from you as well.
Great vid as always! A bit off-topic: you might want to have a glimpse at the Kendryte K210 Boards such as Sipeed MAiX BIT and MAiXduino. These things are awesome and offer tons of power and possibilities such as AI EDGE Computing. Ideal for machine Vision and Hearing. For 30$ they come with Display and Camera and a KPU cappable of 230 Gflops. In Short: MINDBLOWING STUFF - cheers!!! Keep the execellent vids coming ... happy Christmas 😀
