Questions
How big is the IOBoard2021 PCB?
It measures 86 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IOBoard2021 use?
68 parts, built around the TSR 1-2450, TCA9554DBQ, IRLML6344 and PMEG2020EH. 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 IOBoard2021 KiCad files?
From the rustyducks/IOBoard_2021 repository on GitHub, at the commit this page was made from: the board is hardware/IOBoard2021/IOBoard2021.kicad_pcb and its schematic hardware/IOBoard2021/IOBoard2021.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IOBoard2021 design in my own project?
Its repository states no licence, so its author keeps all rights: ask rustyducks before reusing the design.
