Questions
How big is the Heating control PCB?
It measures 142.5 × 72.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Heating control use?
53 parts, built around the VXO7803-500-M-TR, AD5721RBRUZ, AT25DN256-SSHF-B and LM4040DYM3-2.5-TR. 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 Heating control KiCad files?
From the slaesh/trq21-replacement-pcb repository on GitHub, at the commit this page was made from: the board is heating-control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Heating control design in my own project?
Its repository states no licence, so its author keeps all rights: ask slaesh before reusing the design.
