Arduino SIM800L GPRS GSM Module

A breakout board built around the SIM800L cellular module, adding a SIM holder, antenna connection and breakout headers for easier wiring. Provides SMS, voice and 2G GPRS data under AT command control. The same power rules as the bare module apply: supply 3.7-4.2V from a LiPo cell or dedicated buck converter, budget for 2A transmission bursts, and do not run it from an Arduino's 5V rail. Requires an active 2G network on your SIM. Ready-to-wire breakout with SIM holder and headers; SMS, voice and GPRS in one small board; Controlled by simple AT commands; Antenna included
