Questions
How big is the Awohali PCB?
It measures 160 × 100 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Awohali use?
556 parts, built around the TCAN3403DRBRQ1, TXS0104VQRUTRQ1, TPS22996HQDYCRQ1 and M24512-DRMN8TP/K. 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 Awohali KiCad files?
From the DeepSpace00/Awohali repository on GitHub, at the commit this page was made from: the board is hardware/electronics/mainBoard/mainBoard.kicad_pcb and its schematic hardware/electronics/backPanel/backPanel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Awohali design in my own project?
Its repository states no licence, so its author keeps all rights: ask DeepSpace00 before reusing the design.
