Questions
How big is the EX CSB1 PCB?
It measures 65.9 × 52.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EX CSB1 use?
103 parts, built around the CH340C, ESP32-WROOM-32E, AMS1117-3.3 and TLP2361(E. 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 EX CSB1 KiCad files?
From the DCC-EX/EX-CSB1 repository on GitHub, at the commit this page was made from: the board is EX-CSB1.kicad_pcb and its schematic EX-CSB1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EX CSB1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask DCC-EX before reusing the design.
