The only difference between C and D is that I made the holes slightly bigger for the drive FETs in the output over-current protection circuits.

I will be ripping it out in rev C and Read more…

I must have double-dosed my stupid pills the day I laid out the pads for the fuse holders. Apparently they’re 9mm wide and I, for some reason, allocated 6mm Read more…
