This LoRa HAT, suitable for the Raspberry Pi, is based on the SX1268 and covers the 433MHz frequency band. It enables data transmission of up to 5 km via the serial interface.
By using the new generation of LoRa spread spectrum modulation technology, the communication range of the module is up to 5 km long, also supports auto-repeat to transmit longer. Other functions include wake on radio, wireless configuration, carrier detection, communication key and so on.
Compared with normal LoRa modules, the SX1268 LoRa HAT achieves longer communication range, higher rate, lower consumption, better security and anti-interference. It is suitable for various applications such as industrial control, smart home, data acquisition, etc.
