Questions

How big is the Watertemp v1 PCB?

It measures 56 × 90 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Watertemp v1 use?

61 parts, built around the LPC11U24FBD48/301, DS18B20 and SHT21. 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 Watertemp v1 KiCad files?

From the gfroerli/hardware repository on GitHub, at the commit this page was made from: the board is pcb/watertemp_v1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Watertemp v1 design in my own project?

Its repository states no licence, so its author keeps all rights: ask gfroerli before reusing the design.
