Description:
Power supply requirements: 5V-18V,Current 1.5 A or above is required to provide
TTL level serial interface is compatible with 3.3V and 5V microcontroller.directly with 51/STM32/MP430 MCU communication;
Early computer debugging, recommend use CP2102 USB to TTL module to give module power supply and communication;
Using single-chip microcomputer control module, also can through the USB--232 monitoring modulefor instructions and greatly convenient to find the problem,
Standby at around 30 ma you can set the dormant in about 10 ma, low power consumption.
Support for SMS, GPRS data transfer, send MMS, DTMF, HTTP, FTP, the PPP dial-up, and other functions.
At the same time, the hardware contains a reset pin.if Module problems arise, can use this pin reset to solve.
Development board support 2G/3G/4G unicom or mobile phone card.
