Questions
How big is the HeaterMeterPI PCB?
It measures 94.6 × 46.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HeaterMeterPI use?
66 parts, built around the ATMEGA328-PU, BS170 and FQU11P06TU. 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 HeaterMeterPI KiCad files?
From the CapnBry/HeaterMeter repository on GitHub, at the commit this page was made from: the board is eagle/Base/HeaterMeterPI.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HeaterMeterPI 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).
