The board features compact size (smallest GSM module available in the market today) and low current consumption. With power saving technique, the current consumption is as low as 700 µA in sleep mode. It communicates with microcontroller serially via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands. It also supports A-GPS technique which is called mobile positioning and gets position by mobile network. This features make it can be used as tracker module.

SIM800L breakout board is specially designed for project in a small box and powered by 3.7 li-po battery.
