RadioMaster RP3 ExpressLRS Nano Receiver V2 (2.4GHz)

RadioMaster RP3 V2 ExpressLRS 2.4ghz Nano Receiver

The RadioMaster RP series of receivers are designed with size, ease of use and range in mind. Utilizing ExpressLRS 2.4ghz Open-source firmware the RP series of nano receivers deliver features and range today’s pilots have come to expect.

Developed around the ESP8285 MCU and SX1280IMLTRT RF Chip the RP series offer Lora and FLRC 2.4ghz RF links offering incredible range and low latency. With Wifi built in FW updates can be done on your craft without the need to remove the receiver. Binding can be done using a bind phrase meaning no more bind plugs or fiddly button presses while trying to plug in your battery.

The RP3 receiver features a Skyworks SE2431L providing an LNA for improved receiver performance, a PA providing up to 100mw of telemetry performance and antenna switching for antenna diversity.

Except for the RP3 Receiver, we also provide the RP1, RP2 Receiver and RP4TD receiver.

Bullet points

• Optimized PCB design for better heat dissipation.
• LNA for better receiver range.
• PA for better telemetry range.
• Antenna Diversity for improved signal stability and range.
• Solder pads are improved and makes soldering easier.
• V2 version of the RP2 with a TCXO (temperature compensated crystal oscillator)

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.
