Questions
How big is the Dev board v4 mount PCB?
It measures 187.8 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev board v4 mount use?
70 parts, built around the HDSM-441B and SK6812RGBW-BW. 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 Dev board v4 mount KiCad files?
From the hdenraa/element repository on GitHub, at the commit this page was made from: the board is hardware/dev-board-v4-led-7seg/dev_board_v4_mount/.history/dev_board_v4_mount.kicad_pcb and its schematic hardware/basic-esp32s3-dev-board/dev-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board v4 mount design in my own project?
Its repository states no licence, so its author keeps all rights: ask hdenraa before reusing the design.
