A couple of you have had questions regarding dimensions, BOM, etc.

Note that the schematic and BOM are preliminary. There's some (small) chance I'll make changes before submitting.

The dimensions can be considered final. (The form-factor is the same as my F3 boards, although these are narrower as the parts-count is lower.)

The BOM is for a single channel.

Cheers,
Jeff.
