Description:
The serial port is a TTL port that can be connected directly to a microcontroller.
Automatic start when the module is turned on, automatic network search.
On-board display for all signals (signal flash slowly, no signal flashes quickly).
Mini GSM/GPRS breakout board is based on SIM module, support quad band GSM/GPRS network, available for GPRS and SMS data remote transmission.
The board is characterised by compact size and low power consumption. Thanks to the energy-saving technology, the power consumption in sleep mode is only 1 mA.
It communicates with the microcontroller via the UART port and supports commands such as 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands.
Operating voltage: 3.5 ~ 4.2 V.
Quad band 850/900/1800/1900 MHz.
Connect to any global GSM network with any 2G SIM
Make and receive voice calls via a headset or external speaker and electret microphone.
Send and receive SMS messages.
Send and receive GPRS data (TCP/IP, HTTP, etc.)
Scan and receive FM radio broadcasts.
Connection for controlling buzzer and vibration motor.
AT command interface with "auto-build" detection.
