Questions
How big is the WSB Device PCB?
It measures 54 × 29 mm and has 4 copper layers, 0.79 mm thick.
What parts does the WSB Device use?
99 parts, built around the ESP32-C6FH4, ESP32-C6-MINI-1, TPD2E2U06DRL and ESD7351XV2T1G(ES). 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 Device KiCad files?
From the emaneric/Wireless-Serial-Bridge repository on GitHub, at the commit this page was made from: the board is PCB/WSB-Device/WSB-Device.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 Device design in my own project?
Its repository states no licence, so its author keeps all rights: ask emaneric before reusing the design.
