20 M0 Input(weakpull-up) Work with M1 to decide 4 working modes of module (not suspended, if notused, could be grounded).
21 M1 Input(weakpull-up) Work with M0 to decide 4 working modes of module (not suspended, if notused, could be grounded).
22 RXD Input TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can beconfigured as open-drain or pull-up input.
23 TXD Output TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can beconfigured as open-drain or push-pull output
24 AUX Output To indicate module ’ s working status & wakes up the external MCU. During theprocedure of self-check initialization, the pin outputs low level. Can beconfigured as push-pull output (suspending is allowed).
25 VCC - Power supply :2.3~ 5.2V DC
26 GND - Ground
