Milkymist Compatibility - TOFE Expansion board

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.
