SIM900A GPRS GSM Module Development Board w/ Singlechip AD GPS Remote Location Programme

SIM900A GPRS GSM Module Development Board w/ Singlechip AD GPS Remote Location Programme

Description:
- SIM900A+STC12LE5A60S2 structure, STC12LE5A60S2 singlechip dual port, the same with STC12C5A60S2 programme, dual serial port. 3.3V power supply, can directly connect to SIM900A, MAX3232 chip is no need to add
- 32 IO port to lead out singlechip, more input output choice, convenient use
a. 60kFLASH and 1280 bit SRAM operation systme are all ok
b.  With 8 channel 10 bits AD: can detect voltage and current
c.  2 Serial ports : one communicates with GPRS, another can be connected to other UART peripheral
d. With hardware SPI
- U-BLOX NE6M-001 GPS module circuit is reserved, module can be wielded according to users, precicison is better to set as  2.5m, can realize remote location
- 5V power supply and lipo battery power supply, power is at 2A. Original 470uf bile capacitance, more stable power supply. At the same time, 3.3V stablization chip input powering singlechip and GPS can reach 500ma, stronger driving ability
- GPS and GPRS serial port and STC singlechip 2 serial ports can be combined at ease
- Dimension: 63*39mm
