Questions
How big is the MicPreampTest PCB?
It measures 69.9 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MicPreampTest use?
14 parts, built around the S9013. 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 MicPreampTest KiCad files?
From the open-headset-interconnect-standard/ohis repository on GitHub, at the commit this page was made from: the board is KiCAD/MicPreampTest/MicPreampTest.kicad_pcb and its schematic KiCAD/Drawings For Standard Doc/15dB Pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicPreampTest design in my own project?
Its repository states no licence, so its author keeps all rights: ask open-headset-interconnect-standard before reusing the design.
