PIN DEFINITION

No.
NameDirectionFunction
1M0
Input（weak pull-up）

Work with M1 to decide 4 working modes of module (not suspended, if notused, could be grounded).

2M1Input（weak pull-up）

Work with M0 to decide 4 working modes of module (not suspended, if notused, could be grounded).

3RXDInput

TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can beconfigured as open-drain or pull-up input.

4TXDOutput

TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output

5AUXOutput

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).
