The RadioMaster RP series receivers are built-in a TCXO (temperature-compensated crystal oscillator) now, ensuring reliable, stable, and accurate signal reception for superior performance.
The RP1 and RP2 2.4GHz ELRS nano series receivers are open-source receivers based on ExpressLRS. Developed by Jye Smith, they feature ESP8285 MCU and SX1280 RF chip. RP1 has a UFL antenna socket for full-range use, while RP2 has a built-in ceramic antenna, ideal for racing.
Both RP1 and RP2 feature built-in WIFI for firmware updates and configuration via WebUI with your PC or mobile phone.
Ideal for FPV races or Long Range, thanks to low-latency and high-refresh-rate RF modules, RP1 and RP2 are suitable for many models due to their ultra-light and Nano size.
- Improved PCB design for better heat dissipation
- LED on the top side of PCB
- Solder pads improved and easier to solder to
- Built-in TCXO for stability and accuracy
- Compatible with all 2.4GHz ExpressLRS modules and transmitters
EU-LBT VERSION
"Listen Before you Talk" is the abbreviation for a technical feature in radio transmission, which is mandatory for operation within the EU. Therefore, all our remote controls are shipped with this firmware.
This means:
- 4in1 modules are limited to the LBT-enabled protocols FrSKY X/X2 LBT, HoTT LBT, and DSMX
- ELRS modules come pre-installed with EU-approved LBT firmware and are limited to a maximum output power of 100 MW

TCXO (temperature-compensated crystal oscillator)
The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. It results in consistent and reliable signal reception, even in extreme conditions, reducing frequency drift over time, providing long-term stability, and preventing signal degradation.
