Mounting holes #31

What size screws are you planning to use for attaching the PCB? 2.6mm hole would allow M2.5 or M2 screws to be used, but it might be better to use M3 screws and make the holes bigger.

Holes might be too close for components and tracks. Depending on the screws, they might not fit or might damage tracks on the PCB. image image

Mounting holes are still close to tracks and components: image

Bottom left hole is a bit too close to motor driver output pad: image

Don't connect mounting holes to any nets. image

And don't use plating: image

Bottom right hole is not on 1 mm grid.

Also it might be useful to have holes positioned symmetrically. Right now the y-direction spacing is different from x-direction spacing: image

If spacers are going to be used then the capacitors at the bottom are too close to the mounting holes. Capacitors should be moved slightly inwards.
