Questions
How big is the Power channel PCB?
It measures 95.3 × 92.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power channel use?
43 parts, built around the LM358, MCP3208-BI/P, MCP4922-E/P and LM334Z. 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 Power channel KiCad files?
From the johannes51/LabPS repository on GitHub, at the commit this page was made from: the board is HW/boards/power_channel/power_channel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power channel design in my own project?
Its repository states no licence, so its author keeps all rights: ask johannes51 before reusing the design.
