From the project
A board which adds control interfaces and audio for Milkymist compatibility for use with TOFE-8x hosts like the Numato Opsis.
The Numato Opsis board is already very similar to the Milkymist M1 and Mixxeo devices created by M-Labs, but lacks the DJ hardware interfaces. This expansion board adds these missing components.
This board can be ordered from the Numato Opsis page on CrowdSupply.com.
This extension board has the following features;
* AC‘97 compatible audio interface with Microphone, Headphones, Line In + Out (on standard 3.5mm connectors).
