Questions
How big is the VCU V3.2 PCB?
It measures 114 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCU V3.2 use?
170 parts, built around the ATMEGA328P-AU, TJA1051T, OP07 and LTV-847S. 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 VCU V3.2 KiCad files?
From the HKUST-Red-Bird-Racing-EVRT/GEN5_ELEC repository on GitHub, at the commit this page was made from: the board is VCU V3.2/VCU V3.2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VCU V3.2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask HKUST-Red-Bird-Racing-EVRT before reusing the design.
