Questions
How big is the GoodTorch PCB?
It measures 68.6 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GoodTorch use?
106 parts, built around the IR2104PBF, DW01A, HT7333 and TP4056. 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 GoodTorch KiCad files?
From the ShrinathN/GoodTorch repository on GitHub, at the commit this page was made from: the board is Hardware/goodtorch/goodtorch.kicad_pcb and its schematic Hardware/goodtorch/goodtorch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GoodTorch design in my own project?
Its repository states no licence, so its author keeps all rights: ask ShrinathN before reusing the design.
