Since we’ve got the kernel driver, we thought it was time to post a preview of the digital interface hardware. It’s only a preview, the final version will have 8 output channels and 8 input channels. It’ll fit neatly on top of the Raspberry Pi and allow you to sense the world and interface. All inputs and outputs will be on screw terminals so there’s no excuse, everyone can wire up the world with Raspberry Pi and the IO Interface. Demo of the final version will be posted when we finish it.
