  4x2 jumper, Xenia silkscreen image, AP7168, DS1803)

See glitcher.bom.txt for a list of all components needed.

Docs are on the PCB silkscreen.

For U500, use MAX4619CSE+
For U401, use DS1803E-050+ (50k reqd for on-board buck-boost, can be different
                            resistance when not using it)
For U302, use [NOT AP7168-SPG-13] BD00IA5MEFJ-ME2 (-LBH2 is ok too)

For diodes, use eg. https://www.onsemi.com/pdf/datasheet/s110fp-d.pdf (buck-boost),
	https://www.farnell.com/datasheets/2814310.pdf (GPIO Px),
	https://www.farnell.com/datasheets/2721057.pdf (GPIO Sx)

Q1 can be https://www.farnell.com/datasheets/1455134.pdf or so, just make sure
it's the same pinout and package.

Most resistors and small (up to 10uF) capacitors are 0603. Big capacitors (47uF
and up) can be either electrolytic thru-hole or aluminium-polymer SMD.
