Unlock cellular communication for your DIY electronics projects with the SIM800L GSM/GPRS module. This compact and powerful module allows your microcontroller, like an Arduino or Raspberry Pi, to send/receive SMS messages, make/receive calls (may require additional circuitry for audio), and connect to the internet via GPRS. It’s a quad-band module, meaning it can work on GSM networks across the world (850/900/1800/1900MHz). Getting started is pretty straightforward using standard AT commands over a serial UART interface. Perfect for remote data logging, IoT devices, GPS tracking (when paired with a GPS module), and any project needing to break free from Wi-Fi! This version comes with a helical spring antenna and header pins for easy breadboarding or soldering. Operates typically on 3.7V to 4.2V, making it LiPo battery friendly, but be mindful of its peak current draw (up to 2A) during transmission bursts – a good power supply is key.
