[Introduction]:E22-900T22D is a wireless module (UART) with multiple transmission modes, working in the 850.125MHz~930.125MHz, (default 868.125MHz). It features 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 notused, could be grounded). |
2 | M1 | Input(weak pull-up) | Work with M0 to decide 4 working modes of module (not suspended, if notused, could be grounded). |
3 | RXD | Input | TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can beconfigured 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 theprocedure of self-check initialization, the pin outputs low level. Can beconfigured as push-pull output (suspending is allowed). |
6 | VCC | Input | Power supply :2.3~ 5.5V DC |
7 | GND | Input | Ground |
8 | Fixed hole | - | Connect to GND |
9 | Fixed hole | - | Connect to GND |
10 | Fixed hole | - | Connect to GND |
