SIM800C Quad-Band GSM GPRS Module Support TTS/DTMF Board Module with Antenna Development Board
Description:
TTL serial port: module TTL live flat conversion circuit, compatible with all kinds of microcontroller serial port. No direct connection is required.
Audio interface: audio interface pin method leads to convenient test.
TTSDTMF function: text can be directly broadcast through the language and the other side of the telephone button recognition, and 10086 voice station function.
Bluetooth features: Bluetooth 3.0 protocol, enhanced version of Bluetooth antenna signal super strong, support serial port SPP and audio services.
Feature:
Wide voltage power supply: broadband 5~18V DC power supply is efficient and stable.
The power supply range can be adapted to various power sources to facilitate the use of students and project engineers.
Low voltage, high peak current, so the higher the development board power supply voltage, the smaller the current, the smaller the power supply pressure.
Power on automatic boot: power on without buttons or microcontroller control boot, power on directly start, save trouble in the boot process.
Power controllable: truly realize unattended remote control, module power can be controlled by power control pins, high level power supply, low level power off. When the power consumption of the module is close to 0, when the module appears to be dead, it can be restarted through the program control module, without the need to restart the machine power off, the pin defaults to high level, no need to suspend.
Package Included:
1 * SIM800C GSM GPRS Development Module
1 * Antenna
