The first revision of the board four years ago had a big issue where the designer missed all vias but one from one of the fets. They fixed it and ST removed all links, and deleted all schematics, they were too embarrassed. Some of the early boards however are still in circulation sold by some distributors.

Please see the ST response. I don’t believe ST’s engineers are clueless, but mistakes happen in production all the time. Please be polite and considerate to other members of the community.

When I look at the board revision history it mentioned nothing about the early versions of the board having limitations in the maximum current, which is why I assumed that the information provided in the ST forums was incorrect. I think you might be right in the theory that ST was too embarrassed.
That’s pretty awesome!
So you get 1Nm stall torque from the esc.
With 1/10 reduction that’s 10Nm, which is really, really good.

That’s not me I just came across this video.
It shows the thermal limits of this board at 20a with dome cooling.
I was wondering how you got that accent… but decided to keep my mouth shut.

The qvadrans will never be able to compete how?
We were tossing around the idea of making things so the copper areas to and from the mosfets could be flooded with solder, that might turn out to be a good trick to increase current carrying capacity.
But I’ve bought 10 B-G431-ESC1 boards now and used them a fair bit and it really has a lot of issues. There are quality control issues, there is overheating, there are usability and licensing issues, the current measurement signal to noise ratio seems poor, It’s still the best choice among other existing currently easy to get boards, and any design may have at least a few strengths over another.
However, I think the qvadrans will be much better yet also cheaper for 95% of the uses people seem to be pursuing in this board, and if you want to change the design to make it better in some way that you really need, it’s going to be a lot easier than it is for the B-G431-ESC1 board.
