Questions
How big is the Bang PCB?
It measures 50 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bang use?
49 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3, BNO085 and USBLC6-2SC6. 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 Bang KiCad files?
From the ksk1059/- repository on GitHub, at the commit this page was made from: the board is 자작 소총형 게임기/bang.kicad_pcb and its schematic 자작 소총형 게임기/bang.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bang design in my own project?
Its repository states no licence, so its author keeps all rights: ask ksk1059 before reusing the design.
