Questions
What parts does the Powerboard use?
44 parts, built around the SN74HCT245N, TEENSY 4.1, MP2338GTL-Z and SN74LVC245AN. 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 Powerboard KiCad files?
From the Adamh-Tech/PCB repository on GitHub, at the commit this page was made from: the board is Powerboard/_restore_backup_2026-06-24T22-12-58-407/Powerboard.kicad_pcb and its schematic Powerboard/3v3_Stepdown.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Powerboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Adamh-Tech before reusing the design.
