Questions
How big is the TWC PCB?
It measures 40 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TWC use?
45 parts, built around the ESP32-WROOM-32, SN65HVD230D, SHTC3 and SN65HVD11DR(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 TWC KiCad files?
From the jnicolson/TWCController repository on GitHub, at the commit this page was made from: the board is hardware/TWC.kicad_pcb and its schematic hardware/TWC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TWC design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
