SIM800L V2.0 5V Wireless GSM GPRS Module

The SIM800L V2.0 5V module brings full GSM and GPRS cellular connectivity to your microcontroller projects, letting you send SMS, make voice calls, and transfer data over a mobile network from virtually anywhere with cell coverage. Unlike the standard 3.7V SIM800L breakout, this V2.0 version runs directly on 5V and has a built-in voltage regulator and TTL level converter on board, so it can be wired straight to a 5V Arduino or similar board without needing an external regulator circuit or logic level shifter.

It communicates over a simple TTL UART serial interface compatible with both 3.3V and 5V microcontrollers, and is controlled using standard AT commands, making it straightforward to integrate into existing sketches. The module supports quad-band GSM/GPRS coverage, so it works on networks in most countries worldwide, and includes an IPX antenna connector along with a bundled antenna for reliable signal reception. It’s a popular choice for hobbyists and makers building remote monitoring systems, GPS/GSM trackers, SMS-based home automation, IoT alert systems, and any project needing cellular connectivity without relying on WiFi. Note that a Micro SIM card is required and is not included, and a stable power source capable of handling current spikes during transmission is essential for reliable operation.
