Questions
How big is the SLCU PCB?
It measures 95 × 98.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SLCU use?
173 parts, built around the CD4028BNSR, BAT54CDW, 4D03WGJ0102T5E and 4D03WGJ0103T5E. 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 SLCU KiCad files?
From the JMUWRobotics/AMADEE-27 repository on GitHub, at the commit this page was made from: the board is charging_station/KiCad/SLCU/SLCU.kicad_pcb and its schematic charging_station/KiCad/PIHAT/PIHAT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SLCU 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).
