Questions
How big is the Tim PCB?
It measures 121 × 66.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tim use?
187 parts, built around the RP2040, W25Q64JVZPIQ, ADP7105ACPZ-3.3-R7 and ADP7105ACPZ-5.0-R7. 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 Tim KiCad files?
From the UMDBPP/bobot-2 repository on GitHub, at the commit this page was made from: the board is Hardware/Tim/Main board/Main board.kicad_pcb and its schematic Hardware/Moby/Logic_Board/Logic_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tim design in my own project?
Its repository states no licence, so its author keeps all rights: ask UMDBPP before reusing the design.
