The RP series of receivers are designed with compact size, ease of use, and extended range in mind. Utilizing ExpressLRS 2.4GHz open-source firmware, the RP series nano receivers deliver reliable performance and long-range connectivity that meets the expectations of modern pilots. Built around the ESP8285 microcontroller unit (MCU) and the SX1280IMLTRT RF chip, the RP series supports both LoRa and FLRC 2.4GHz RF protocols, providing excellent range and low latency. Built-in Wi-Fi enables convenient firmware updates directly on your model without removing the receiver. Binding is simplified with a bind phrase feature, eliminating the need for bind plugs or complicated button presses during setup. The RP3 receiver includes a Skyworks SE2431L chip, integrating a low-noise amplifier (LNA) for enhanced receiver sensitivity, a power amplifier (PA) supporting up to 250mW telemetry output, and antenna switching for improved signal stability through antenna diversity.
