Questions
How big is the DI Lambda DITOS controller PCB?
It measures 28 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DI Lambda DITOS controller use?
35 parts, built around the ATMEGA32U4-MU, USBLC6-2SC6 and AO3400. 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 DI Lambda DITOS controller KiCad files?
From the koi-science/DI-Lambda-schematics-avr repository on GitHub, at the commit this page was made from: the board is DI-Lambda-DITOS/DI-Lambda-DITOS-controller/DI-Lambda-DITOS-controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DI Lambda DITOS controller design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
