Either open the board you want in EasyEDA and use the one-click order in the fabrication menu, or I could assemble one of the v5.5 bare boards I have on hand (very similar, just lacking the refinements listed in that last thread post).
It is possible the current sensors will be too noisy for your ultra-silent use cases. Oversampling helps a lot, but as seen in the thread, I was still getting some pretty wild signals at higher speeds. I can’t tell any difference in audible motor noise compared to B-G431B-ESC1, but you’d probably be best served by shunt sensors with INA240 Calibrating inline current sense for the ESP32s3 - #7 by Antun_Skuric
Yeah, I’d planned to request that once it’s fully validated. It’s theoretically complete, but not quite time to make a big announcement yet.
The buck outputs are accessible via the LVin and VDRV pins on the aux connector.
The pin accessibility issue is one reason I’m not too fond of generic boards. For real-world use it’s really nice to have them grouped by purpose with connectors, and that necessitates having some idea of how they’ll be used. The Qvadrans approach of surrounding the CPU with header pins gives more flexibility, but quickly turns into an incomprehensible wire nest. Nonetheless it would be nice to get the remaining unused pins accessible somewhere. And using 2.54mm pitch for pin headers and connectors would be fine if size is of no concern.
For my application (robo-bird), size is critically important, as is cost. I really only need two high power motors, and 6 lower power, but since I wasn’t able to significantly reduce the size or cost without them being drastically lower power (though in hindsight, I probably could have with the Qvadrans mosfets), I just copy-pasted the high power driver. Gooser 4 and 5 both fulfill my needs for that project, so any future development can relax the size constraint.
