Questions
How big is the Top board panel PCB?
It measures 170 × 135.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Top board panel use?
262 parts, built around the LPC1759FBD80, MCP6001OB, PCA9685PW and NCP1117DT33G. 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 Top board panel KiCad files?
From the mod-audio/mod-hw-duo repository on GitHub, at the commit this page was made from: the board is hw-design/top-board/top-board-panel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Top board panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask mod-audio before reusing the design.
