Specifications
| What it is | The receiver in the aircraft. It pairs to an ExpressLRS transmitter you already own — this is not the radio in your hands |
|---|---|
| Protocol | ExpressLRS v3, pre-installed. Binds to any ELRS 2.4 GHz transmitter: RadioMaster TX16S, TX12, Zorro and the rest |
| Hardware | ESP8285 with an SX1280 RF chip — the open-source reference pairing, not a closed module |
| Refresh rate | 25 Hz up to 500 Hz, or F1000. Low rates buy range, high rates buy latency, and you pick per model |
| Output | CRSF, which every Betaflight-class flight controller reads and ArduPilot takes on a serial port |
| Power | 5 V |
| Size | 13 × 11 × 3 mm |
| Weight | 2.2 g including the antenna. Small enough to go almost anywhere in the airframe, which is the point of a nano receiver |
| Antenna | 65 mm 2.4 GHz T antenna on a U.FL socket, so it can be swapped for any other U.FL antenna |
| Setup | Built-in WiFi. Update the firmware and change settings from a phone or a laptop through its own web page, with nothing plugged in |
| In the box | RP1 receiver, 65 mm U.FL T antenna, manual |
| Fits | Every frame we sell, from the 2-inch cinewhoop to the Q705 |
| Manufacturer | RadioMaster |
