SIM800C GSM GPRS Module 5V/3.3V TTL Development Board IPEX With Bluetooth And TTS For Arduino

RWF 14,400.00


SIM800C is a complete Quad-band GSM/GPRS solution in a SMT type, which can be embedded in the customer applications. SIM800C supports Quad-band 850/900/1800/1900MHz, it can transmit Voice, SMS and data information with low power consumption.


Power input: DC5V or received by a lithium battery input VBAT and GND.

Supports MCU level: 5V / 3.3V for TTL logic

(Such as the common 51 and the for arduino is 5v, STM32 is the 3.3v)

Antenna use: IPEX antenna interfaces, you can use the version PCB antenna or antenna IPEX-SMA- peppers

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

PWR: This pin can turn down or turn off the module

GND: power supply ground

VBAT: lithium battery input pin, 3.3v-4.4v
