Questions
How big is the PDM PCB?
It measures 86 × 99 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PDM use?
148 parts, built around the MLX91221KDC-ABR-020-SP, KF50BDT-TR, BTS50010-1TAE and BU4S584G2-TR. 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 PDM KiCad files?
From the patwitt/PGRacingElectronics repository on GitHub, at the commit this page was made from: the board is PDM/PCB/PDM_v3/PDM.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PDM design in my own project?
Its repository states no licence, so its author keeps all rights: ask patwitt before reusing the design.
