- Supply V-MCU, which is the same power supply voltage to your MCU, normally 5V or 3.3V
- Pin Definiiton
VCC - board VCC and V-MCU GND - board GND TXD - board R RXD - board T
- If board us on power key button, it will auto power up, otherwise hold down power key for 3-5 seconds to boot
- Check power led should be constant on, and Net led blink status will change after network registered.
- Serial output +CPIN: READY means sim card detect correctly.
- Please try following AT commands, notice commands end up with \r\n
