DESCRIPTION :
Introduction
- This product is a Raspberry Pi expansion board based on SX1268/SX1262 chip, a wireless serial port module with LoRa modulation function.
- With multi-level relay to achieve ultra-long-distance communication, low power consumption wake-up communication, encrypted transmission, etc.
- This product uses a private protocol and does not support LoRaWAN.
Features
- Support global license-free ISM 433/470/868/915MHz frequency band.
- Supports wake-on-air, that is, ultra-low power consumption, suitable for battery-powered applications.
- Support point-to-point transmission, broadcast transmission, channel monitoring, and multi-level relaying for ultra-long-distance communication.
- Support RSSI signal indicator for evaluating signal quality and improving communication network.
- Support the LBT function, and monitor the channel environmental noise before sending, which can greatly improve the communication success rate of the module in harsh environments.
- LoRa spread spectrum technology, up to 84 channels/81 channels (SX1268/SX1262).
- Support waking on radio, online configuration, carrier sense, automatic relay, communication key, low power sleep.
- In an ideal environment, the communication distance can reach 5KM.
