[Introduction]:E22-400T30S is a wireless serial port module (UART) based on SEMTECH's SX1262 RF chip. It has multiple transmission modes, 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.
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).
6 VCC Input Power supply :3.3~ 5.5V DC.
7 GND Input Ground.
8 NRST Input Module reset pin, low reset
9 GND Input Ground.
10 NC Input Can be suspended.
11 NC Input Can be suspended.
12 NC Input/output Can be suspended.
13 NC Input/output Can be suspended.
14 NC Input/output Can be suspended.
15 GND - Ground.
16 GND - Ground.
17 GND - Ground.
18 ANT Output High frequency signal output, 50Ω characteristic impedance.
