SIM800C Gsm modul SMS Fejlesztőkártya GPRS támogatás STM3251 Super A6SIM900A
SIM800C Gsm Module SMS Development Board GPRS Support STM3251 Super A6SIM900A
Description
Wide-voltage power supply: The wide-band 5~18V DC power supply is efficient and stable, and the power supply range is enlarged to adapt to various power supplies, which is convenient for students and project engineers. High, the smaller the current, the smaller the power supply pressure.
Automatic power-on after power-on: power-on does not require buttons or single-chip microcomputer to control power-on, and it starts directly after power-on, eliminating the troublesome power-on process
The power supply can be controlled: truly realize unattended remote control, the module power supply can be controlled through the power control pin, high-level power supply, low-level power off. When the power is off, the power consumption of the module is close to 0. When the module crashes, the module can be restarted through the program control. There is no need to restart the machine after power off. The pin defaults to high level, and it can be left floating if it is not used.
TTL serial port: module TTL with level conversion circuit, compatible with various single-chip serial ports. There is no need to convert the direct connection. .
Audio interface: The audio interface is led out by pin header, which is convenient for testing.
TTSDTMF function: You can broadcast the text directly through the language and recognize the other party's keys during a call to realize the function of the 10086 voice station.

Bluetooth function: Bluetooth 3.0 protocol, the enhanced version of the Bluetooth antenna signal is super strong, supports serial port SPP and audio services, etc.
