Questions
How big is the PSU PCB PCB?
It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PSU PCB use?
118 parts, built around the ATMEGA32U4RC-AU, OPA2170AID, OPA4170AID and INA219AID. 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 PSU PCB KiCad files?
From the ThomasVDD/SmartSupplyMini repository on GitHub, at the commit this page was made from: the board is PCB/PSU_PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PSU PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask ThomasVDD before reusing the design.
