Questions
How big is the MLX90393 board PCB?
It measures 75.8 × 59 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MLX90393 board use?
35 parts, built around the MLX90393SLW-ABA-011-SP, AP2112K-3.3 and BSS138. 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 MLX90393 board KiCad files?
From the purepani/MagneticSensorTracking repository on GitHub, at the commit this page was made from: the board is circuit/MLX90393_board/MLX90393_board.kicad_pcb and its schematic circuit/MLX90393_board/MLX90393_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MLX90393 board design in my own project?
Its repository states no licence, so its author keeps all rights: ask purepani before reusing the design.
