One of the benefits of having a easily-generated CAD model of a PCB with components, it becomes possible to test possible interference and clearance of connectors and cables. In this case I was worried the Eurorack power cable (2×5 IDC connector) might interfere with the micro-USB plugged into the ItsyBitsy M4. So far looks good. So I sent the board to fab and should have some to play with next week.
