Circuit diagrams and firmware source code for Gboard DIY keyboards

A thermal sensors comparison research project.
ProPrj therminator 2026-01-14 is an open-source printed circuit board by gucio321, from the gucio321/therminator repository on GitHub. It is a 2-layer board of 82.6 × 91.3 mm with 14 parts on 11 nets, routed with 135 tracks and 0 vias.
This is a repository containing resources for my enviroumental physics project.
The main goal of this project is to compare various types of thermal sensors in terms of their accuracy.
The expected result of the experiment is a decent set of data obtained automatically with a microcontroller setup.

It measures 82.6 × 91.3 mm and has 2 copper layers, 1.6 mm thick.
14 parts. 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.
From the gucio321/therminator repository on GitHub, at the commit this page was made from: the board is board/ProPrj_therminator_2026-01-14.kicad_pcb and its schematic board/ProPrj_therminator_2026-01-14.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask gucio321 before reusing the design.
