Designed specifically for use with our Nexus Helicopter Flybarless control unit and compatible with all CRSF/S.BUS enabled flight controllers the RP3-H ExpressLRS receiver comes with a built-in TCXO and an integrated housing design that makes the receiver tougher and ready to mount in modern helicopter frames. With the RP3-H receiver, you can get reliable, stable, and accurate signal reception, which enhances your flight experience and allows for superior performance even in demanding environments.
The RP3-H receiver uses the Skyworks SKY66112 power amplifier to increase telemetry performance, the PA provides up to 100mw of telemetry power, and antenna switching for antenna diversity. It is developed around the ESP8285 MCU and SX1281IMLTRT RF Chip, offering Lora and FLRC 2.4GHz RF links that provide incredible range and low latency. With Wifi built-in, firmware updates can be done on your craft without the need to remove the receiver.
The receiver has connectors for easy connection without soldering. It also includes a battery voltage sensor in the 4-35V range.
Firmware Options: LBT & FCC – please select as required.
