Questions
How big is the MPPT Charger PCB?
It measures 160.2 × 53.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MPPT Charger use?
72 parts, built around the TPS61022RWUR, TPS61088RHLR, BQ24650RVAT and KLDX-0202-A. 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 Charger KiCad files?
From the jfhardyii/PCB_Designs repository on GitHub, at the commit this page was made from: the board is MPPT Charger/KiCAD Files/MPPT Charger.kicad_pcb and its schematic Filter/KiCAD Files/Filter_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MPPT Charger 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).
