Questions
How big is the Voltage adjuster panel PCB?
It measures 94 × 75 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Voltage adjuster panel use?
609 parts, built around the LDK130PU-R, LMK107B7105KA-T, LMK107BJ475KA-T and CRG0603F5K1. 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 Voltage adjuster panel KiCad files?
From the RasmusKoit/voltage_adjuster repository on GitHub, at the commit this page was made from: the board is voltage_adjuster_panel.kicad_pcb and its schematic voltage_adjuster.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Voltage adjuster panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask RasmusKoit before reusing the design.
