RadioMaster RP3 V2 ExpressLRS 2.4 GHz nano-receiver

RadioMaster RP3 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.

The RadioMaster RP series of receivers are designed with size, ease of use and range in mind. Using open source ExpressLRS 2.4 GHz software, the RP series of nano receivers delivers the features and range today's pilots expect.

Developed based on the ESP8285 microcontroller and the SX1280IMLTRT RF chip, the RP series features 2.4 GHz RF Lora and FLRC links, offering incredible range and low latency. Thanks to built-in Wi-Fi, firmware updates can be performed on the device without having to remove the receiver. No more plugging in or pressing buttons unnecessarily when trying to connect batteries.

The RP3 receiver is equipped with a Skyworks SE2431L chip providing LNA for improved receiver performance, PA for telemetry performance up to 100mW, and antenna switching to provide antenna diversity.

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.
