Cool build!Since this is a li-on battery, how do you manage to protect it from over discharge?I am looking for a reliable power supply for SIM800L module with discharge protection and other safety features, do you have any good suggestions?Thanks!
what power supply module are you using to convert AC to DC to power up the boards?It looks like you forgot to mention its details and amazon link.

Well, I had this Richduino-UNO-Basic-Arduino-Board with the same problem, I just figured out a way to make it work, I opened the serial monitor and passed a few random gibberish by setting "carriage return" and 19200 baud from the Arduino IDE interface.After doing that, I closed the serial window and tried to upload the program and it uploaded successfully.
