Description
Add cellular connectivity to your embedded engineering projects with the ultra-compact SIM800L GPRS GSM Module Core Board. Ideal for remote data logging, smart vehicle tracking, home automation, and SMS alarm systems, this core board packages complete GSM/GPRS functionality into a miniature, breadboard-friendly footprint.
Operating on quad-band frequencies (850/900/1800/1900MHz), the SIM800L module connects to standard 2G cellular networks worldwide (and compatible 2G fall-back networks). It communicates with host microcontrollers via a simple TTL level UART serial port, allowing easy control using standard AT commands. The board includes an onboard micro-SIM card slot and comes with helical and PCB antenna options to ensure stable signal reception.
