Overview1. This is a raspberry pi lora hat based on sx1268, covers 433mhz 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 sx1268 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.Features1.Standard raspberry pi 40pin gpio extension header, supports raspberry pi series boards2. Onboard cp2102 usb to uart converter, for serial debugging3. Bring the uart control interface, for connecting host boards like arduino stm324. 4X led indicators, easy to check the module status5. Lora spread spectrum modulation technology, up to 84 available signal channel, longer communication distance, more robust to interference6. Auto multi-level repeating, suit for ultra long range communication, allows multi network on the same region7. Low power consumption features like deep sleeping and wake on radio, ideal for battery-powered applications8. Customizable communication key which wont be retrieved, greatly improves the security of user data9. Support lbt, monitoring the signa...
