Cool, Jussi, leaves nothing to be desired.
What about the nuts? Do they have the needed height to tighten the screws or do one have to care not to bend the M4?

Good work Jussi!
How does one order the 32v version?
And is this incorporated in the latest FW versions?
Cheers
James

Thanks guys!
Actually the ones I have now are all 32V versions - the voltage sensing circuit on M4 is good up to 35V as I remember. There will later be an option to choose between the 2 versions.
Tilman, if you look at the wiki page, you will see that a set of washers are needed (and supplied with the board) to keep the board from buckling or warping when the screws are tightened. A plastic spacer is on order, but chinese NY has it delayed, so the washers are the only solution now.

You will need different firmware to use brush-less motors.
aqv7.0.r442.b1848-hwv8.6-quatos-ext_esc works for this as does the non-quatos version.
I'm curious about this board as well. I have one of Joerg's BLDC boards and this seems to have a slight edge in terms of features. I like that it has the ability to power other devices with either 3v3 or 5v -- seems helpful for things like doing a FPV quad. Also it has voltage sense, which is helpful -- rather than running it straight off the battery directly to M4. The CAN bus connectivity is great for future proofing. However, I think I'll continue with my Joerg BLDC and maybe go with the upcoming M4 PDB, which would allow for larger multi-rotors than a quad.

All boards or kits shipped now are 32V versions. Will add details to the shop and wiki page shortly.
