BetaFPV SPI FrSky D8 Receiver (CC2500) for Whoop FCs

BetaFPV's SPI receiver board adds radio control to its whoop flight controllers supplied without a built-in receiver: the F4 1S AIO FC and the Lite 1-2S brushless FC (No RX versions). It plugs straight onto the board and weighs 0.43 g, giving a tiny whoop FrSky D8 control on 2.4 GHz with no soldering.

Key features

• CC2500 radio chip set to FrSky D8 by default; FrSky D16 is not supported
• Can be switched to Futaba S-FHSS with a firmware change, following BetaFPV's guide
• Pin connector, plug and play — nothing to solder on the flight controller

Specifications

• Chip: CC2500
• Protocol: FrSky D8 (default), Futaba S-FHSS after a firmware change
• Frequency: 2.4 GHz
• Weight: 0.43 g
• Size: 13.5 × 9 mm

Your radio has to transmit FrSky D8, for example through a CC2500-based multi-protocol module or a FrSky radio that still offers D8 mode. D16-only and ELRS radios will not bind to it.
