[Introduction]:E22-230T22S is a wireless serial port module (UART) based on SEMTECH's LoRa solution radio frequency chip. It has multiple transmission methods and works in the (220.125MHz~236.125MHz) frequency band; it adopts a new generation of LoRa spread spectrum technology, compared with SX1278 , longer distance, lower power consumption, and smaller size; supports air wake-up, wireless configuration, carrier monitoring, and relay networking functions.

Input(weak pull-up)

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

22RXDInput

TTL UART inputs, connects to external (MCU, PC) TXD output pin.

23TXDOutput

TTL UART inputs, connects to external (MCU, PC) RXD output pin

24AUXOutput

     Used to indicate the working state of the module;

   The user wakes up the external MCU and outputs low level during power on self-test initialization; (can be suspended)
