Like with their previous 30x30 4in1 ESC boards which had hardware design issues, it seems that Holybro have now also recognised that there were hardware issues with the previous revisions of their 20x20 Tekko32 F3 4in1 Mini ESC (45A) and they've released a new "Revision C" version which has a separate daughterboard containing the logic circuit components, just like they did with their 30x30 4in1 ESCs to address issues with those. It's reported that this ESC is now working fine with the daughterboard architecture and BLHeli_32 32.7.2 firmware.

I wonder if this will solve the slight desync issue I have with my 4" long range. Is this supposed to eliminate the problems people are having with bi-directional d-shot? I might have to look into this. Thanks for the info Snow.

Holybro have apparently stated that this board fixes all the known issues and they explicitly mentioned that the bi-directional DShot issue is fixed with this particular board revision. You do however also need to be running the 32.7.2 version of the BLHeli_32 firmware which is still currently in beta.
