Questions
How big is the Charge Controller PCB?
It measures 139.7 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Charge Controller use?
163 parts, built around the CH340C, ESP32-WROOM-32, XL7005A and IR2104PBF. 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 Charge Controller KiCad files?
From the jharvey/Charge_Controller repository on GitHub, at the commit this page was made from: the board is Charge_Controller.kicad_pcb and its schematic Charge_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Charge Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask jharvey before reusing the design.
