[Introduction]:E32-433T33D is a wireless serial port module (UART) based on SEMTECH's SX1276 RF chip. It has transparent mode, working in the 410~441MHz (default 433MHz), LoRa spread spectrum technology.
Pin No | Pin Item | Pin Direction | Pin Application |
---|---|---|---|
1 | M0 | Input(weak pull-up) | With M1, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used). |
2 | M1 | Input(weak pull-up) | With M0, the four working modes of the module can be determined (it cannot be suspended, and it can be grounded if it is not used). |
3 | RXD | Input | TTL UART input, connect to external TXD output pins; Can be configured as drain open circuit or pull up input, see parameter Settings |
4 | TXD | Output | TTL UART output, connect to external RXD input pin; Can be configured as drain open circuit or push - pull output, see parameter Settings |
5 | AUX | Output | Used to indicate the working status of the module; The user wakes up the external MCU and outputs low level during self-test initialization; Can be configured as drain open output, or push-pull output, see parameter Settings (can be suspended) |
6 | VCC | Input | Positive reference of module power supply, voltage range: 3.3V ~ 5.2V DC |
7 | GND | Input | Ground |
