SIM800L module + Antenna Mini GPRS GSM Module

SIM800L is a minuscule GSM module that offers 2G GSM/GPRS data, and supports SIMCOM enhanced AT commands.

SIM800L is a miniature cellular module which allows for GPRS transmission, sending and receiving SMS and making and receiving voice calls. Low cost and small footprint and quad band frequency support make this module perfect solution for any project that require long range connectivity. After connecting power module boots up, searches for cellular network and login automatically. On board LED displays connection state (no network coverage - fast blinking, logged in - slow blinking).

NOTE: Be prepared to handle huge power consumption with peak up to 2A. If the power supply can’t cater the requisite current well, the module will shut down/reset in the middle of the action.
