Questions
How big is the Main board array PCB?
It measures 81.3 × 91.4 mm and has 2 copper layers, 1 mm thick.
What parts does the Main board array use?
528 parts, built around the AMS1117-3.3. 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 Main board array KiCad files?
From the andy666chang/model-car repository on GitHub, at the commit this page was made from: the board is main_board/main_board_array.kicad_pcb and its schematic led_bar_board/led_bar_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main board array design in my own project?
Its repository states no licence, so its author keeps all rights: ask andy666chang before reusing the design.
