Here we are using a 2596 buck converter for providing a constant voltage of 4.2 Volts as the GSM SIM800L module is a power hungry device that will require more current while using the GPRS. To know ...

Have you ever worked with the SIM800L module for your projects? It's a handy tool for tasks like making calls and sending SMS, but sometimes it can be tricky to get it working smoothly. In this guide, ...

Linux system with a UART serial port, or Raspberry Pi with Raspberry Pi OS (this library has been tested with Buster and Bullseye). External power supply for the SIM800L (using the Raspberry Pi 5V ...

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...

If you are looking for a compact GSM/GPRS module, you can get the SIM800L from most eBay traders. It is not the most judicious choice, but you can build your own basic GSM projects with a cheap modem ...
