Questions
How big is the CM4IOUSB3 PCB?
It measures 160 × 90 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CM4IOUSB3 use?
136 parts, built around the 74LVC1G07SE-7-MS, AP3429KTTR-G1, AP22653W6 and PCF85063AT/AAZ. 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 CM4IOUSB3 KiCad files?
From the FIRSTRoboMax/PCB repository on GitHub, at the commit this page was made from: the board is altered/CM4IOUSB3.kicad_pcb and its schematic altered/CM4IOUSB3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CM4IOUSB3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask FIRSTRoboMax before reusing the design.
