Questions
How big is the AtInverter v2 PCB?
It measures 83.8 × 94.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AtInverter v2 use?
116 parts, built around the ATMEGA328P-PU, R-78HE5.0-0.3, IR2302PBF and TMCS1108A4BQDRQ1. 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 AtInverter v2 KiCad files?
From the bcarrillo1051/Atinverter repository on GitHub, at the commit this page was made from: the board is KiCad/Projects/AtInverter_v2/AtInverter_v2.kicad_pcb and its schematic KiCad/Projects/AtInverter_v1/AtInverter_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AtInverter v2 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).
