Questions
How big is the Controller Analog PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Controller Analog use?
37 parts, built around the S-89713B-K8T2U and NJM2825F-TE1. 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 Controller Analog KiCad files?
From the EosinY/Electronicload-TestController repository on GitHub, at the commit this page was made from: the board is Controller_Analog.kicad_pcb and its schematic Controller_Analog.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller Analog design in my own project?
Its repository states no licence, so its author keeps all rights: ask EosinY before reusing the design.
