Questions
How big is the Tsukuba challenge PCB?
It measures 90 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tsukuba challenge use?
96 parts, built around the ISOW1044BDFMR, CCG30-24-12S, L7805 and USBLC6-2SC6. 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 Tsukuba challenge KiCad files?
From the hcmos/open_rover-cnt_pcb repository on GitHub, at the commit this page was made from: the board is tsukuba_challenge.kicad_pcb and its schematic CAN_Transceiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tsukuba challenge design in my own project?
Its repository states no licence, so its author keeps all rights: ask hcmos before reusing the design.
