RadioMaster RP1 V2 ExpressLRS 2.4 GHz nano-receiver

RadioMaster RP1 V2 ExpressLRS 2.4 GHz nano-receiver

RadioMaster RP Series receivers now feature a built-in TCXO temperature-compensated crystal oscillator that ensures reliable, stable and accurate signal reception, allowing for excellent performance in demanding environments and enhancing the flight experience.

RP1 and RP2 ELRS nano 2.4 GHz series receivers are open source receivers based on ExpressLRS. First developed by Jye Smith of the ExpressLRS development team, the Nano receivers feature an ESP8285 microcontroller and an SX1280 RF chip. RP1 has a UFL antenna socket enabling the use of a full-range antenna. RP2 has a built-in ceramic antenna that is super light and small, perfect for racing.

RP1 and RP2 have built-in Wi-Fi functionality, so you can update firmware over Wi-Fi and configure the receiver via the built-in WebUI using your computer or mobile phone.

Due to the low latency and high refresh rate RF module, RP1 and RP2 are perfect for FPV or long range racing. They fit many models due to their ultra-light design and Nano size. These receivers will fit almost anywhere!

TCXO (Temperature Compensated Crystal Oscillator)

TCXO ensures high stability and accuracy of frequency control, compensating for temperature changes. This ensures consistent and reliable signal reception, even in extreme temperatures. It also reduces frequency drift over time, ensuring long-term frequency stability and preventing signal degradation.
