[Introduction]:E220-900T30D adopts a new generation of LoRa spread spectrum technology and a wireless serial port module (UART) designed based on the LLCC68 chip scheme. It has a variety of transmission methods, works in the (850.125 ~930.125MHz) frequency band (default 873.125MHz), 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 TXD output pin. |
| 4 | TXD | Output | TTL UART outputs, connects to external RXD input pin. |
| 5 | AUX | Output | Used to indicate the working status of the module; the user wakes up the external MCU, and outputs low level during power-on self-check initialization; (can be left floating) |
| 6 | VCC | Input | Voltage range: 3.0~5.5V DC |
| 7 | GND | Input | Ground |
| 8 | Fixed hole | - | Fixed hole |
| 9 | Fixed hole | - | Fixed hole |
| 10 | Fixed hole | - | Fixed hole |
| 11 | Fixed hole | - | Fixed hole |
