Questions
How big is the UGC Main R4K PCB?
It measures 125.7 × 76.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the UGC Main R4K use?
168 parts, built around the RP2040, MCP3002-I/MS, CH340K and GD25Q80EEIGR. 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 UGC Main R4K KiCad files?
From the HandHeldLegend/GC-Ultimate repository on GitHub, at the commit this page was made from: the board is HW/Projects/Main_R4K/UGC_Main_R4K.kicad_pcb and its schematic HW/Projects/Main_Prototype/UGC_Main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UGC Main R4K design in my own project?
Its repository states no licence, so its author keeps all rights: ask HandHeldLegend before reusing the design.
