Small Quanta schematic for the Z8B USB daughterboard, revision 1A, only 34.6 KB in PDF form. It covers the secondary board carrying USB ports rather than the mainboard, so expect connector pinouts, the cable link to the motherboard and any filters or protection parts. Useful when a port does not work or the 5 V supply on the daughterboard is shorted, as you can trace each line back to the interconnect cable. Check that the small board carries the Z8B code and revision 1A, and pair it with the matching mainboard schematic.
