Questions
How big is the NB3 hindbrain PCB?
It measures 57 × 22.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NB3 hindbrain use?
147 parts, built around the FT2232HQ, RUM001L02T2CL, CLMVC-FKA-CLBDGL7LBB79353 and LD1117S12TR-HXY. 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 NB3 hindbrain KiCad files?
From the NoBlackBoxes/LastBlackBox repository on GitHub, at the commit this page was made from: the board is boxes/fpgas/NB3_hindbrain/NB3_hindbrain.kicad_pcb and its schematic boxes/audio/NB3_ear/NB3_ear.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NB3 hindbrain design in my own project?
Its repository states no licence, so its author keeps all rights: ask NoBlackBoxes before reusing the design.
