Questions

How big is the PS ChargerInterfacePCB PCB?

It measures 82.3 × 79.4 mm and has 2 copper layers, 1.58 mm thick.

What parts does the PS ChargerInterfacePCB use?

140 parts, built around the TPS613771RYHR, IRLML0030TRPBF, NVMFWS1D7N04XMT1G-VB and 1N5819HW-7-F-01. 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 PS ChargerInterfacePCB KiCad files?

From the lhr-solar/PS-ChargerInterfacePCB repository on GitHub, at the commit this page was made from: the board is Hardware/PS-ChargerInterfacePCB.kicad_pcb and its schematic Hardware/12V-24VBoostConverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PS ChargerInterfacePCB design in my own project?

Its repository states no licence, so its author keeps all rights: ask lhr-solar before reusing the design.
