Known issues
Revision A uses pins that are used by BeagleBone emmc interface. Therefore following cut and paste changes must be made:
P8 B23 -> P8 B19 [GPIO0_22]
P8 B25 -> P8 B26 [GPIO1_29]
P8 B5 -> P8 B7 [GPIO2_2 ]MISO and MOSI pins are swapped, it can be corrected on software side. TODO: how to do it.

Questions
How big is the Usbasp cape PCB?
It measures 86.4 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usbasp cape use?
24 parts, built around the INA219AID and SN74CBTLV3253D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Usbasp cape KiCad files?
From the thinnect/beaglebone-usbasp-cape repository on GitHub, at the commit this page was made from: the board is usbasp-cape.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbasp cape design in my own project?
Its repository states no licence, so its author keeps all rights: ask thinnect before reusing the design.
