My Arduino does not power on when I put the SIM800L to 5V and when I switch to 3.3V, my SIM800L does not work. If I use powerbank and an IN-4001 diode to regulate 5V, will it work? Is it a good long term or will I be forced to use another power source? I have another idea. I'm also planning to use a Romoss Ares 10 Mini powerbank with 2 USB output with 5V 2.1A to power Arduino and connect other wire to SIM800L in breadboard. Do you think it can work?
@TechToTinker2 жыл бұрын
SIM800L is power hungry device so it should be power with a separate external power supply with ATLEAST 2A current capability. With regards in using powerbank, I cannot give you answer with that because I haven't tried it perhaps you could try it on your own. I would suggest to use an external power supply 1 for Arduino and another 1 for the gsm module.

Hi George, (It seems that people are calling you by that name!) This seems to be a useful video. I have just bought this GSM module and will try it as soon as I am satisfied about safe voltage levels. I wanted to ask you why you had no problems with supplying *and driving* the module with 5 volts. I understand using a common silicon diode to drop the voltage by 0.6V for the supply. I will probably put a large capacitor after the diode to supply the burst current. But for driving the the RXD input, would a diode and a pull-down resistor be good enough? Have you some experience with that method? Many thanks.
@TechToTinker3 жыл бұрын
@Mike Van In, I would suggest to better use a proper external power supply between 3.4V to 4.4V with 2A power supply. For the Rx pin of SIM800L, you can use a voltage divider circuit to lower voltage level.

This video, and many other tutorial videos, show the RxD pin connected directly to the Tx pin of a 5V Arduino ? The RxD pin on the SIM800L has a MAXIMUM voltage level of 2.8V. It needs a potential divider network to reduce the 5V signal from the Arduino to the 2.8V input on the SIM800L module. I have no doubt it works without, but it is stressing the SIM800L beyond acceptable limits, and I wonder how long it will last.

That's a great Videa TechToTinker, but your description of the pin assignments doesn't seem to match the label on the back of the SIM800L. Pin 3 (from the top) is labelled as RST, whereas you described it as RXD, then you only describe five pins, when there are actually six (NET, VCC, RST, RXD,TXD and GND according to the label). I have ordered an SIM800L, but it hasn't arrived yet, so I can't verify whether your description or the labels are correct, but it might be an idea for you to confirm please :-) Do we need to do anything with the RST pin, such as tie it high or low perhap, or will the the SIM800L work OK without it connected, as appears to be the case?
@TechToTinker3 жыл бұрын
Hi @Michael Benn, NET is not actually a pin where pin headers will be connected. NET is where you connect the external helical antenna. That's the reason, I begin pin assignment from VCC as pin 1. You can leave the RST pin without connection to microcontroller. its sole purpose is for resetting the SIM800L.I believe, it has a pullup resistor in the module. You have the option to tied it to microcontroller's RESET pin or you can control it manually. Thank you and cheers.

can i use it like a tracker gps , i mean that it can send a location to the phone with sms message
@TechToTinker3 жыл бұрын
@Yassine Charrour, SIM800L is a GSM module only it can make or receive call and receive or send SMS. However, you can attach a gps module to your MCU and send the GPS coordinates with the GSM module. Another option could be is to use the 3G internet capability of SIM800L and use the network tower location as reference for the coordinates. This option is not accurate. I have not tried it also, so I do not know how to make it. I hope this helps you. Cheers.

Sir,there is a 3.5 volt in ardruino uno. Can we use it
@TechToTinker2 жыл бұрын
No, and Arduino has 5V and 3.3V only not 3.5V. You should use external power supply that can provide 3.4 to 4.4V with a minimum current capacity of 2A. Less than that, your project will not work.
@bob-ny6kn Жыл бұрын
5V power? It's a 3.7 (4.0) vdc module.

You may watch again this video to make it more clear and easy to understand. Basically, you need to send AT commands to SIM800L to let it do something like sending sms or making voice call. The source code is good for testing sim800 if its functional. You might like to watch this instead for more detailed explanation: kzbin.info/www/bejne/fnPNmnmjgNhomac Cheers.

Try sending AT in your serial monitor. You may refer to this manual for more details: www.elecrow.com/wiki/images/2/20/SIM800_Series_AT_Command_Manual_V1.09.pdf
