RP1 ExpressLRS 2.4GHz Nano Receiver
The RadioMaster RP series now features a built-in TCXO (Temperature-Compensated Crystal Oscillator) for improved frequency stability and accuracy. This helps maintain reliable and consistent signal reception, even in demanding operating conditions.
The RP1 2.4GHz ELRS Nano receiver is an open-source receiver based on ExpressLRS, featuring an ESP8285 MCU and SX1280 RF chip. Its U.FL antenna connector allows the use of an external full-range antenna, providing greater flexibility for different RC builds.
The RP1 also features built-in Wi-Fi, allowing you to update firmware wirelessly and configure the receiver through its built-in WebUI using a PC or mobile device.
With its low-latency, high-refresh-rate RF link, the RP1 delivers highly responsive control performance. Its ultra-lightweight, nano-sized design makes it easy to install in a wide range of RC models where space and weight are limited.
Features
- Improved PCB Design: Enhanced PCB layout improves heat dissipation for more stable operation.
- Upgraded Rigid Antenna: Provides improved durability and reliable RF performance.
- 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: The 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.
