Overview
1. This is a Pi LoRa HAT based on SX1262, covers 915MHz frequency band. It allows data transmission up to 5km through serial port.
2. 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.
3. Comparing with normal LoRa modules, the SX1262 LoRa HAT achieves longer communication distance, higher rate, lower consumption, better safety and anti-interference. It is suitable for various applications such as industrial control, smart home, data collection, etc.
