When your robot needs range and responsiveness, choosing a single radio is a compromise. This compact joystick remote stuffs three links into one board—ESP32’s Wi-Fi/BLE for convenience, an nRF24L01+ for snappy 2.4 GHz control, and an SX1276-based RFM95W for kilometer-class LoRa.
It’s hackable, printable, and all the files are on GitHub.
