Design Requirements
This page collects the generic hardware requirements for all Flight Controller designs for Rotorflight.
The actual Reference Designs for Rotorflight-2 can be found here.
For an FC to be fully supported by Rotorflight-2 (RF2), it must follow one of the Reference Designs.
Betaflight Guidlines
Rotorflight is based on Betaflight, and thus has the same basic requirements for the hardware.
Please read the Design Guidelines for Betaflight first.
