- In this video, I am testing two sim800l modules with 5v power supply. If you have issue like "Sim800l not connecting to the network" or "Sim800l Powering Issue" then this video will be helpful to you. Sim800l gsm module sometime works very strange "sim800l blinks 7 times" this is because power problem.
I made 5 test for two different sim800l modules with different configurations of a capacitor (16v 470uf). And I am able to run both sim800l modules perfectly.
I know you have the question that, is it safer to give 5v dc directly from Arduino or laptop USB port to the module. Let's see, I will connect 5v directly to sim800l gsm module

Hello, thank you very much, I was trying to get it to connect to the network without success, but thanks to your video I was able to do it, thank you very much.
Glad to hear that
I connected a capacitor of 10uF and powered it through my usb port, it worked! Thank you
that's great
Ahmad, you are my friend :) This video solved an annoying problem. Thank you a lot!
MOST WELCOME
This is the only solution working for me. Many thanks
so nice of you
This is confusing, but works, I'm able to connect for the first time
Thanks... I can move forward now
It also very confusing for me. but amazingly it works fine
What problem did you faced before
Thank you Ahmad Bhai... It's solved my network issue SIM800L V2.0 module. But diode also required across capacitor?
To safely power the sim800 module with 5V, put a diode in series on 5V line, just before the capacitor. The cap can be 860-1000mF.
thanks for sharing your knowledge
what's the value of the dioda exactly? Please
@@samrev292it may be IN4007?
in my case, i have used step down buck convertor and i had set it to 4v, it still facing the power issues(7 times blink and reset), then i have the increased the voltage to 4.35v still i had faced the power issue. but totally, i removed the step convertor and connected directly to 5v by using this capacitor trick. finally it worked!!!
May I know the sim card that you used is 4G?
I did this and connected capacitor 470 to the module capacitor, he replied, thank you
Which power supply ur using
so nice of you
5v mobile phone charger
@@badrinathmurugesan7375 Connect the Arduino to a computer, use it, or use a mobile charger
AMAZING. it's work ..thank you very much
thanks
Thanks! Solved my problem
so nice of you
it works!!! You are the best!
By God's grace mine worked, the set-up I had though was using two 18650 batteries in series-so total voltage was around 7.4V, and used a buck converter stepping down the voltage to around 4V and connecting the output of the buck converter, directly towards the SIM800L Mini GSM module, I made sure that the wires I used was as short as I can enable and used AWG24 wires, I did not use any capacitors, and everything worked fined, I even used 5G capable SIM card and it worked well with no problems; hopefully those working on this had theirs working, God Bless
you are right must use best quality wires also power supply must as close to the sim800l as possible.
you can directly attach single 18650 without buck convertor. just try it. I have use single 18650 battery in my most of projects without using buck converter
@@AhmadLogs yes indeed 😄, one 18650 is already enough, I used two 18650 in series set-up because of the project I worked on
@@stephencarlm.calatrava8877 hmmmm.. very nice
bro if you mind me asking. what sim did you use? are you from the philippines?
@@vincepapolonias1599 yes po, from the Philippines, I used a 5G TM SIM card, the GSM module uses the micro SIM size, though the GSM module itself operates at 2G using a 5G SIM card did not cause any problems, it worked fine
U r really genius super genius
Many many thanks
I keep burning the module . I bought a second one and it does not turn on again... I am doing only 3.7 battery.
what isa difference of method 1 and 2?
Salam Ahmed, could you please make a video of the sim800c module, can it be connected directly with 5v?and what is the function of ttl pin?
I dont have sim800c module right now. but you cannot connect it directly to the 5v. no idea about the ttl pin.
sim800l v2 can be connected directly to the 5v pin
Does it has a side effect for a long time use? Like damaging the sim modul as the example
using a capacitor in parallel with the power supply of the SIM800L module can have some benefits, such as reducing the noise and ripple in the power supply, which can improve the performance of the module. However, it is important to choose the right value of capacitor and to properly install it to avoid any negative effects on the module.
In general, using a capacitor in parallel with the power supply should not damage the SIM800L module, as long as the capacitor is correctly selected and installed. However, if the capacitor is too large, it may cause excessive inrush current when the module is first powered on, which can potentially damage the module. Similarly, if the capacitor is not installed properly, it could create a short circuit or other electrical problems that could damage the module.
@@AhmadLogs Really helpful buddy. Thank u so much
I used lithium 3.7 v battery...but still facing not connected to network problem .
use short length of wires. connect sim800l directly to sim800l without using breadboard
que cambia en el metodo uno con el dos?
4.3 volts. Set the voltage under load.
4.0v is best
Man this module is a pain in the arse, weird operating voltage range, 2A surges that needed to be handled with.. are there any better alternative for GSM/GPRS connection?
try sim800L V2. (5v)
I just use 3.3-5v range of supply, capacitors 100uf,470uf,200uf,1000uf,1500uf,2200uf, step ups, li-on, 1n4001 diodes and moooore and this module didn't work and today i destroy it because maybe i get damaged module from shop...
I can't return because I have already soldered the module and the seller would say that I damaged it, the next one I will buy, I will only connect the power supply through the crocodile clips and I hope that the module will work
i hope you it worked with you
Hello, I wanted to ask
If we use the sim800i module, can we use Bluetooth headset?
you just give it try. unfortunately, I don't have any idea
@@AhmadLogs Thank you for your reply
Hello sir, if I want to do GSM calling and my GSM blink non stop mean don't have enough power and the solution is capacitor 16v? And need to do command for calling and SMS if not doing that cannot work?Please sir I need your explanation for my project gsm laser security
you need 3.7v and at least 2000mAh battery for powering sim800l. if your gsm blink non stop, then its mean that
1. there is some issue with your sim card that you have inserted in the module.
2. there is some issue with your gsm module antenna.
3. or your gsm module might be damaged. just try another sim800l
Hello, did the same thing but mine doesn`t work, i have a 18650 3.7V battery connected to it and Arduino but id won t connect to network, tried everything, need help please! Without SIM card csq range between 29-31 when i plug the sim card, it sees it and csq is 0 0. I just don t understand
try to change the sim card. or verify the sim card if it is working or not, by inserting it into the phone. only 2g sim card will work. try with another sim800l
Hi Sir , i followed the same but still my sim800l not working. I used 470uf but 25v instead of 16v . Is that the problem?
this is not a proper way to power sim800l. it is just a trick. you need proper power supply like 3.7v battery
BIG BOSS
thanks
how much the current of your usb laptop i am using usb that used to be phone charger but it fail
usb is capable of provide enough current to the gsm module. also you can use 2A rating mobile phone charger, I have tested it.
Hello sir, I have a problem in the sim800l module version 2, while looking for the signal to restart continuously... How to solve the problem?
it is power supply issue. use 5v 2A power supply
Use separate power supply for sim800l v2 and use 1000uf 6.3V capacitor across Vcc and gnd pins at module. It will work
I have sim800l v2 and the led keeps blinking. its pretty for it to connect to a network it only happend about 3 times. What do you think is the cause problems. Please help😭
Can we connect Neo-6m antenna to sim800l
No, the Neo-6m GPS antenna cannot be connected directly to the SIM800L module. The SIM800L module does not have a GPS receiver built-in and cannot be used for GPS tracking without an external GPS module.
Can I use SIM while it is working?
yes
Hy . Can I use 100v 100uF?
just give it a try
this means we can connect directly to 5 volts????????
sometimes?
ON USB only 4,4 volts?
yes.
Will sim 800L support 4g sim?
no
Do not use 5V power to power on the SIM800L module under any circumstances. It will damage the module in the long run.💥
Hello sir my sim 800l is connecting to network but it is not communicating with arduino i have tried multiple circuits still its not working pls help i contacted u on whatsapp too
1. the rx or tx pin of sim800l might damaged.
2. you did not select the correct baudrate
OR NOT
you'll kiul sim800l with 5v. it must be powered by 4V!
Bonjour
I have SIM800L and doesn't work with 3G/4G SIM. THIS INFORMATION is really?
yes, its only works with 2g. I have 3g SIM that have 2g also
@@AhmadLogs do you now any module SIM work with 3G sim
