This GSM/GPRS development board is based on SIM800C chip supporting bluetooth function and AT command control via the serial port. On-board SIM card slot and support 850/900/1800/1900MHz quad band can be used worldwide. It is equipped with 5V/3.3V logic converter circuit compatible with most MCU breakout board to obtain the SMS and TTS function.

Pin Description

  • 5V: power supply pin, the only input DC5V, used to power the board.
  • V_TTL: access control board microcontroller core target voltage of 5V / 3.3V (according to its own microcontroller is much to distinguish – kernel v), this pin is used to convert the GSM module board TXD and RXD for the corresponding TTL logic.
  • GND: power supply ground
  • TXD: send pin serial port module, TTL level (not directly connected to RS232 level)
  • RXD: receive pin serial port module, TTL level (not directly connected to RS232 level)
  • DTR: Data Terminal Ready
  • SPKP: Core Audio output pin
  • SPKN: Core Audio output pin
  • MICN: Core Audio input
  • MICP: Core Audio input
  • RI: Ring core pin tips
  • VRTC: RTC pin external battery
  • GND: power supply ground
  • PWX: This pin can turn down or turn off the module
  • GND: power supply ground
  • VBAT: lithium battery input pin, 3.3v-4.4v
