KakuteH743-wing with bdshot

warp2 · April 19, 2024, 9:25am

Hi, I have a KakuteH743-wing and would like to flash it with 4.5.1 plane with Bdshot for a TailSitter build. If I am correct there is no bdshot version on the Firmware site?
Would it be possible to create it for the KakuteH743-wing board for planes?
thank you very much

If you mean the KakuteH7-Wing firmware, it already has bdshot (on first 8 outputs).

(BIDIR is written for a pair of channels, so there are four BIDIR labels corresponding to four pairs of bdshot-enabled channels)
