Questions
How big is the Debugger pcb rev4 PCB?
It measures 17.8 × 68.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Debugger pcb rev4 use?
45 parts, built around the CH32F103R8T6, H7VL10B, 0402L050SLKR and GT-USB-7010ASV. 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 Debugger pcb rev4 KiCad files?
From the byobc/debugger-rev4 repository on GitHub, at the commit this page was made from: the board is pcb/debugger-pcb-rev4.kicad_pcb and its schematic pcb/debugger-pcb-rev4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Debugger pcb rev4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask byobc before reusing the design.
