Questions
How big is the PSU Control PCB?
It measures 29 × 45.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PSU Control use?
18 parts, built around the M2.5, FCSL76R005DER, AWHSH124D00G and T2N7002BK,LM. 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 Control KiCad files?
From the G1874/pcb-ender3v2-psu-ctrl repository on GitHub, at the commit this page was made from: the board is PSU_Control.kicad_pcb and its schematic Main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PSU Control 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).
