Questions
How big is the Chiller PCB?
It measures 94 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chiller use?
72 parts, built around the ESP32-WROOM-32, 74LVC2G14GW, BSS138 and MBRA210LT3G. 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 Chiller KiCad files?
From the bullestock/chiller repository on GitHub, at the commit this page was made from: the board is pcb/chiller.kicad_pcb and its schematic pcb/addon/addon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chiller design in my own project?
Its repository states no licence, so its author keeps all rights: ask bullestock before reusing the design.
