Questions
How big is the Mcp23008-led PCB?
It measures 55 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mcp23008-led use?
35 parts, built around the MCP23008-E/P. 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 Mcp23008-led KiCad files?
From the tronixio/modules repository on GitHub, at the commit this page was made from: the board is Kicad/gpio-mcp23008-led/mcp23008-led.kicad_pcb and its schematic Kicad/gpio-breadbaord/main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mcp23008-led design in my own project?
Its repository states no licence, so its author keeps all rights: ask tronixio before reusing the design.
