Questions
How big is the Workbench PCB?
It measures 99.9 × 99.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Workbench use?
70 parts, built around the ESP32-DEVKITC-VE, 74HC595, ULN2803A and IRL520PBF. 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 Workbench KiCad files?
From the crgarcia12/electronics-workbench-controller repository on GitHub, at the commit this page was made from: the board is PCB/workbench-02/workbench.kicad_pcb and its schematic PCB/workbench-01-jlcpcb/workbench.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Workbench design in my own project?
Its repository states no licence, so its author keeps all rights: ask crgarcia12 before reusing the design.
