[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.
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. |
