RadioMaster RP3 V2 ExpressLRS 2.4GHz Nano Receiver

The RadioMaster RP3 V2 is a 2.4GHz ExpressLRS nano receiver for FPV quads, wings and other space-conscious builds that want ELRS range and low latency in a compact package.

Key features

• Built around the ESP8285 MCU and SX1281 RF chip for ExpressLRS LoRa and FLRC links.
• Skyworks SE2431L front end adds an LNA for receive range and a PA for up to 100mW of telemetry power.
• True antenna diversity across two 65mm T antennas improves signal stability when the model changes orientation.
• Built-in TCXO keeps frequency stable and accurate across temperature swings for a more reliable link.
• Wi-Fi onboard for firmware updates without removing the receiver; bind-phrase binding needs no bind plug.
