Mic test: common questions
How big is the Mic test PCB?
The Mic test measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Mic test?
307 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Mic test design files?
From the jbrryhooves/sound-compass repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Mic test design in my own project?
The repository has no license, so all rights stay with jbrryhooves. Use it as a reference, and ask the author before reusing the design.
