RadioMaster RP1 V2 TCXO ELRS 2.4GHz Nano Receiver

The RadioMaster RP1 V2 TCXO is an ultra-compact 2.4GHz ExpressLRS receiver built for whoops, micro drones, and weight-conscious racing or freestyle builds. Upgraded from its predecessor, this V2 iteration integrates a Temperature Compensated Crystal Oscillator (TCXO) to ensure rock-solid RF frequency stability and reliable telemetry, regardless of extreme heat from adjacent electronics or winter flight conditions.

Key features

• Built-in TCXO prevents packet loss and frequency drift during temperature fluctuations.

• Features a standard U.FL (IPEX1) connector, allowing easy swaps or replacement of the included 65mm T-antenna.

• Open-source ExpressLRS architecture delivers exceptional range, low latency, and high refresh rates.

• Sub-gram bare board weight minimises impact on ultralight toothpicks and cinewhoops.
