Questions
How big is the Brian Dai PCB?
It measures 74.5 × 69.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Brian Dai use?
104 parts, built around the MCS1802GS-50-Z, AP62150WU, MMC5983MA and MS5611-01BA03. 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 Brian Dai KiCad files?
From the rice-eclipse/AFSElec repository on GitHub, at the commit this page was made from: the board is IndividualFolders/Brian Dai/Main/Main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brian Dai design in my own project?
Its repository states no licence, so its author keeps all rights: ask rice-eclipse before reusing the design.
