Ebyte Sx1278 Iot Module Lora Smart Parking Sensor

[IC]:SX1278

[Frequency]:410~441MHz

[Power]:21~30dBm

[Distance]:8.0km

[Interface]:UART

[Weight]:8.2±0.1g

[Introduction]: E32-433T30D is adopts LoRa spread spectrum technology, with this technology the module can transmit much longer distance than similar products under the same power with better anti-interference performance.

Pin No Pin Item Pin Direction Pin Application
1 M0 Input(weak pull-up) Work with M1& decide the four operating modes. (Floating is not allowed, can be ground)
2 M1 Input(weak pull-up) Work with M0 & decide the four operating modes. (Floating is not allowed, can be ground)
3 RXD Input TTL UART inputs, connects to external TXD (MCU, PC) 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 open-drain output or push-pull output. (Floating is allowed)
