Questions
How big is the TEC PCB?
It measures 172 × 85 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TEC use?
298 parts, built around the LTC1923EUH#PBF, DAC108S085CISQ, LP3985-30B3F and 2N7002PW. 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 TEC KiCad files?
From the brianpepin/tec_controller repository on GitHub, at the commit this page was made from: the board is hardware/TEC.kicad_pcb and its schematic hardware/LTC1923Channel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TEC design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
