I used the REYAX RYLR998 as the LoRa radio on both ends of this build because it makes long-range serial communication really approachable for beginners. Once you’ve got UART wired up, you can send sensor data as a simple payload and read it right back on the other side.
Pros
- +Long-range, low-power LoRa link that doesn’t need Wi‑Fi or internet
- +Simple UART interface works great with ESP32
- +Receiver output includes useful stats like RSSI and SNR
Cons
- -Requires correct UART wiring (TX/RX crossed) and matching settings on both modules
- -You need to pay attention to 3.3V logic levels
