Questions
How big is the Eval board-1 buck regulator PCB?
It measures 57.2 × 37 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Eval board-1 buck regulator use?
50 parts, built around the GRM32ER71C226KEA8, UCH1V470MCS1GS and PA4343.102NLT. 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 Eval board-1 buck regulator KiCad files?
From the MicroType-Engineering/eval-board-1_buck-regulator repository on GitHub, at the commit this page was made from: the board is kicad_proj/eval-board-1_buck-regulator/eval-board-1_buck-regulator.kicad_pcb and its schematic kicad_proj/eval-board-1_buck-regulator/eval-board-1_buck-regulator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eval board-1 buck regulator design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
