My initial intention was to power the SIM800L module from a 3.7-V Li-ion battery (because it draws a lot of current for proper operation) and power the Arduino Uno from a 9-V alkaline battery. Later, ...

Before you can use the Sim800L Arduino Library, you need to physically connect the SIM800L module to your Arduino board. ... It is important to note that the SIM800L module requires a stable power ...

3,7V battery used to power the SIM800L Module. Sim900A will also work but might need some changes in code. Log in ... Nano, Mini all work for this project without changing any single line in code and ...

The system is made using sensors like GPS Neo 6m, Arduino, GSM Sim800L. Here, different IoT platforms, Different IoT tools, sensors, different programming libraries, APIs usages, server hosting and ...

There are 12 connections in total (6×2 rows) on the SIM800L module and, surprisingly, one row contains all of the connections required to interface with a microcontroller like the venerable Arduino!
