Questions
How big is the ModuleBack PCB?
It measures 48.3 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ModuleBack use?
80 parts, built around the TL072, LM2950G-3.3, 2SC1815 and BAT48JFILM. 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 ModuleBack KiCad files?
From the ikechangexentrick/function_generator repository on GitHub, at the commit this page was made from: the board is hw/ModuleBack.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ModuleBack 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).
