RadioMaster RP Series Receivers

Name: RadioMaster DBR4 Dual band Xross Gemini ELRS LBT Receiver
Brand: RadioMaster
SKU: 62040
Price: 37.90 EUR
Availability: OutOfStock

The RadioMaster RP series receivers are built-in a TCXO (temperature-compensated crystal oscillator) now, which ensures reliable, stable, and accurate signal reception, allowing for superior performance in demanding environments and enhancing the flight experience.

RP1 and RP2 2.4GHz ELRS Nano Series Receivers

The RP1 and RP2 2.4GHz ELRS nano series receivers are open-source receivers based on ExpressLRS. The Nano receivers, first developed by Jye Smith from the ExpressLRS development team, feature ESP8285 MCU and SX1280 RF chip. The RP1 has a UFL antenna socket for full-range antenna use. The RP2 has a built-in ceramic antenna which is super light and small in size and ideal for racing.

Features of RP1 and RP2

WIFI built in for firmware upgrades by WIFI and configuration via the built-in WebUI with your PC or mobile phone.
Low-latency and high-refresh-rate RF module, ideal for FPV races or Long Range.
Ultra-light and Nano size, suitable for many models and can fit just about anywhere.

TCXO (Temperature Compensated Crystal Oscillator)

The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation. Click to learn more about the TCXO.
