Questions
How big is the UnoInverter PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UnoInverter use?
159 parts, built around the IR2101PBF, LM7812CT and IRFZ44N. 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 UnoInverter KiCad files?
From the erikAWTO/UnoInverter repository on GitHub, at the commit this page was made from: the board is UnoInverter/UnoInverter.kicad_pcb and its schematic UnoInverter/UnoInverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UnoInverter 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).
