Details

Built for lightweight FPV builds, the nano receiver pairs a compact board with a T antenna for dependable 2.4GHz links.

A clean, compact layout helps keep installs tidy on tight frames while still using the CRSF receiver protocol.

At only 0.8g, the single-sided PCB keeps solder points accessible for fast wiring on 2–5 inch builds.

Support for 100mW telemetry and cable-free WiFi flashing makes updates and tuning easier at the bench or in the field.

Designed to work with most 2.4G ELRS transmitter modules for quick pairing and straightforward upgrades.
