I am working on my own soldering station based on HAKKO T12 cartriges. Electronics is related to the one found on EEVBlog forum https://www.eevblog.com/forum/reviews/t12-stm32-v2-1s-soldering-station-controller-schematic-etc/
Firmware will be built from scratch. Work in progress.

Questions
How big is the Isense PCB?
It measures 20.3 × 15.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Isense use?
11 parts, built around the OPA237NA/250G4. 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 Isense KiCad files?
From the kloper/st12 repository on GitHub, at the commit this page was made from: the board is kicad/balcony/isense/isense.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Isense design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
