## Todo
- add enable mosfets with led indicator for each channel
- make each channel a parametrised sub-schematic?
- Figure out how to copy the layout for each channel down the board
- Figure out exactly how wide the board can be and still fit in the case
- add decoupling caps for the ina219s
- Add solderable jumper footprints for the address select, one that's one by default

Questions
How big is the Usb c psu PCB?
It measures 24.3 × 92.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb c psu use?
19 parts, built around the PCF8574T and DMN3404L. 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 Usb c psu KiCad files?
From the TomHodson/pcbs repository on GitHub, at the commit this page was made from: the board is usb-c_psu/usb-c_psu.kicad_pcb and its schematic usb-c_psu/usb-c_psu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb c psu design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
