Questions
How big is the Autoradiator PCB?
It measures 66 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Autoradiator use?
12 parts, built around the WEMOS D1 MINI and DRV8870DDA. 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 Autoradiator KiCad files?
From the rothn/autoradiator repository on GitHub, at the commit this page was made from: the board is pcb/autoradiator/autoradiator.kicad_pcb and its schematic pcb/autoradiator/autoradiator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Autoradiator design in my own project?
Its repository publishes it under the Apache-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).
