[Introduction]:E220-900T30S is a new generation of LoRa wireless serial port module(UART), based on Semtech's original LLCC68 chip design. It has a variety of transmission methods, works in the (850.125~930.125MHz) frequency band(default 873.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.

1
No. Name Direction Function
1 M0 Input(weak pull-up) Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded).
2 M1 Input(weak pull-up) Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded)
3 RXD Input TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can be configured as open-drain or pull-up input. Ground
4 TXD output TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output
5 AUX output To indicate module ’ s working status & wakes up the external MCU.During the procedure of self-check initialization, the pin outputs low level.Can be configured as push-pull output (can be suspended).
