Questions
How big is the Board1 PCB?
It measures 58 × 67 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Board1 use?
24 parts, built around the DRV8876PWP, BNO085 and J107F1CS1224VDC.36. 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 Board1 KiCad files?
From the iRobotics-Pacbot/Electrical repository on GitHub, at the commit this page was made from: the board is pacboard2024/board1.kicad_pcb and its schematic Bat_manage/Bat_manage.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask iRobotics-Pacbot before reusing the design.
