ADC: common questions
How big is the ADC PCB?
The ADC measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ADC?
52 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the ADC design files?
From the will-fritz/4-ch-mic-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ADC design in my own project?
Yes, under the terms of its GPL-3.0 license, which will-fritz chose for the repository.
