Questions
How big is the Mppt PCB?
It measures 120.1 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mppt use?
156 parts, built around the ADM3055EBRIZ, INA210CQDCKRQ1, EPC2307 and XT60PW-M. 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 Mppt KiCad files?
From the dimembermatt/MPPT-Design repository on GitHub, at the commit this page was made from: the board is hw/mppt.kicad_pcb and its schematic hw/comm_can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mppt design in my own project?
Its repository states no licence, so its author keeps all rights: ask dimembermatt before reusing the design.
