Interface description:
GND: Power ground
VCC_IN: Power supply pin, input DC5V-20V
RI: Ring indicator
DTR: Data terminal preparation
TXD: TTL serial port transmission
RXD: TTL serial port receive
U2_R: module serial port 2 receive
U2_T: module serial port 2 send transmission
V_M: connect to the core voltage (5V/3.3V,it depend on your MCU) of MCU for level match(generally, NC also be OK for this pin)
ADC: ADC detection
SPP: Audio output positive
SPN: Audio output negative
MC-: Audio input negative
MC +: Audio input positive
PWR: Power enable or disable(enable when low level)
BAT: lithium battery input pin, 3.3v-4.4v
Basically instructions:
The SIM800C mainly controlled by AT commands, so just find a USB convert to TTL serial port module,and 5V,GND,TXD,RXD pins connect to VCC_IN, GND,RXD, TXD pins of SIM800C
When the module is started, the indicator LED flashes once every 1 seconds, and after a period of time, the indicator LED flashes once every 3 seconds, it means the SIM800C start works normally.
