SIM800L GSM GPRS Module Mini GSM / GPRS breakout board is based on SIM800L module, supports quad-band GSM/GPRS network, available for GPRS and SMS message data remote transmission.
The board features compact size and low current consumption. With power saving technique, the current consumption is as low as 1mA in sleep mode.
It communicates with microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands.
Working Voltage: 3.5~4.2V
Quad-band 850/900/1800/1900MHz
Connect onto any global GSM network with any 2G SIM
Make and receive voice calls using a headset or an external 8 speaker and electret microphone.
Send and receive SMS messages.
Send and receive GPRS data (TCP/IP, HTTP, etc.) .
Scan and receive FM radio broadcasts.
Lead out buzzer and vibrational motor control port.
AT command interface with “auto baud” detection.

SIM800L GSM GPRS Module Specification:

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).

NOTICE: Be prepared to handle huge power consumption with peek up to 2A. Maximum voltage on UART in this module is 2.8V. Higher voltage will kill the module.
