RP1 & RP2 ExpressLRS Nano Receivers
The RadioMaster RP series receivers now feature a built-in TCXO (Temperature-Compensated Crystal Oscillator), providing reliable, stable, and accurate frequency control. This helps maintain consistent signal reception and reliable performance in demanding operating conditions.
The RP1 and RP2 2.4GHz ELRS Nano receivers are open-source receivers based on ExpressLRS. Developed with the ExpressLRS ecosystem, both receivers feature an ESP8285 MCU and SX1280 RF chip for low-latency, high-refresh-rate wireless performance.
The RP1 features a U.FL antenna connector, allowing the use of a full-range external antenna. The RP2 uses an integrated ceramic antenna, providing an exceptionally compact and lightweight design that is particularly well suited for racing applications.
Both the RP1 and RP2 feature built-in Wi-Fi, allowing convenient firmware updates and receiver configuration through the built-in WebUI using a PC or mobile device.
With their low-latency, high-refresh-rate RF link and ultra-compact nano-sized design, the RP1 and RP2 deliver highly responsive performance while fitting into a wide variety of RC builds.
Features
- Improved PCB Design: Enhanced PCB layout improves heat dissipation for more stable operation.
- Top-Mounted LED: The LED is positioned on the top side of the PCB for better visibility.
- Improved Solder Pads: Redesigned solder pads make installation and soldering easier.
- Built-In TCXO: A temperature-compensated crystal oscillator provides improved frequency stability and accuracy.
- Wide ExpressLRS Compatibility: Compatible with all 2.4GHz ExpressLRS modules and transmitters with built-in 2.4GHz ExpressLRS.

TCXO (Temperature-Compensated Crystal Oscillator)
The built-in TCXO provides excellent frequency stability and accuracy by compensating for temperature fluctuations. This helps maintain consistent and reliable signal reception across a wide range of operating temperatures.
By minimizing frequency drift over time, the TCXO also helps maintain long-term frequency stability and reliable RF performance, reducing the risk of signal degradation.
