Questions
How big is the WSB PC PCB?
It measures 16 × 15 mm and has 6 copper layers, 0.8 mm thick.
What parts does the WSB PC use?
35 parts, built around the 74LV1T34GW, ESP32-C6-MINI-1, TPD2E2U06DRL and GT-USB-8012A. 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 WSB PC KiCad files?
From the emaneric/Wireless-Serial-Bridge repository on GitHub, at the commit this page was made from: the board is PCB/WSB-PC/WSB-PC.kicad_pcb and its schematic PCB/WSB-Device/MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WSB PC design in my own project?
Its repository states no licence, so its author keeps all rights: ask emaneric before reusing the design.
