These parts are not required for a normal build - in general: don't buy them! They would go to the greyed-out locations specified as DNF ("do not fit") in the BOM above. If you want them anyways, e.g. for a special usecase, you can also copy & paste them into your mouser cart:

You can manually add these to your cart using the links below. If you are buying a midiphy essential kit, these should be included already. If you are buying plain PCBs, these are necessary to complete your build.
