SIM800L GPRS GSM Module with Wire Antenna

SIM800L Module is a miniature cellular GSM / GPRS breakout board that allows GPRS transmission, sending and receiving messages, and making and receiving calls. This module supports quad-band GSM/GPRS network, which is available for GPRS and SMS data remote transmission. 

Having a small footprint, quad-band frequency support and low price make it perfect for any project that requires long-range connectivity. The device uses a serial communication method, so it communicates with almost every controller via the UART port. After giving voltage supply module boots up, search for the cellular network, and login automatically.

Instruction

• This module is power-hungry and consumes 2A (peak)
• The maximum recommended voltage in UART in this module is 2.8V. More than this will kill the module
• If the power supply can not cater the required current well, the module will shut down.reset in the middle of the action

LED and indication

• Fast blinking: no network coverage or searching
• Slow blinking: logged in
• Not blinking: check the power
