Doublecheck footprint for 100uF driver caps - size works for up to 63V caps ? #8

If we want to operate the drivers with higher voltage (DRV8825 can do up to 45V), the caps should do that. IIRC, the current ones are 35V but we'd need 50V or 63V types here - see if that footprint can do it.

Yes. We also need maximum of 9mm height constraint to fit between connectors.

There is Digikey PCE5024CT-ND which is 6.3mm diameter (current footprint) and 8mm high for 50V and rated 2000h@105C. A winner :)

No board change needed.
