This is a Raspberry Pi LoRa HAT based on SX1268, which covers the 433MHz frequency band. It allows data transmission up to 5km through the serial port.
By utilizing the new generation LoRa spread spectrum modulation technology, the communication distance of the module is as long as 5km, also supports auto repeating to transmit longer. Other features include Wake on Radio, wireless config, carrier sensing, communication key, and so on.
