RadioMaster RP1 V2 ExpressLRS 2.4ghz Nano Receiver RX

RadioMaster RP series receivers have a built-in TCXO — a temperature-compensated crystal oscillator. It is used to stabilize the frequency and support receiver operation in different temperature conditions.

RP1 and RP2 2.4 GHz ELRS nano series receivers are based on the open-source ExpressLRS project. They are equipped with an ESP8285 microcontroller and an SX1280 RF chip. RP1 has a UFL antenna connector for connecting an external antenna. RP2 has a built-in ceramic antenna and a compact format.

RP1 and RP2 have built-in Wi-Fi, which can be used to update the firmware and configure the receiver via WebUI using a compatible PC or mobile device.

Thanks to their compact format and low weight, RP1 and RP2 receivers can be used in various FPV models where the ExpressLRS 2.4 GHz protocol and the corresponding connection to the flight controller are supported.

Features

• The printed circuit board design provides heat dissipation during operation.
• Updated antenna for compatible receiver configurations.
• The LED is located on the top side of the printed circuit board.
• Solder pads are adapted for wire installation.
• Built-in TCXO — temperature-compensated crystal oscillator. 

TCXO (temperature-compensated crystal oscillator)
TCXO is used to stabilize the frequency while taking temperature changes into account. This helps reduce frequency drift during receiver operation and maintain correct radio module operation within the manufacturer’s specifications.
