[Introduction]:E22-900T22D is a wireless module (UART) with multiple transmission modes, working in the 850.125MHz~930.125MHz, (default 868.125MHz). It features LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.

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).
