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
