Review on 📡 REYAX RYLR896 Lora Module SX1276 UART 868MHz 915MHz Antenna Command FCC NCC by Paul Abs

Excellent quality. Bought two, they worked so got two more. Your documentation is perfect, concise and to the point. They should be able to talk to each other right away, but basically just give them an address: AT+ADDRESS=1234, make sure they're on the same network: AT+NETWORKID. = 2 and they should be able to communicate: AT + SEND = 0.5, HelloArduino sends 5V and RYLR896 receives 3.3V, so you need to level it to control it with Arduino. I would recommend buying two USB to TTL converters to learn how to communicate with them. All in all a great product, highly recommended.
