I’ve been looking over the Github content for the expansion board, and have a question. As many of us will want to replace this card with our own containing additional hardware we want to add to the system, will more be released that just the PDF schematics? Any design files? If it is indeed the intent that we build our own mods for the system this would be greatly helpful. I can of course measure everything out once I receive the hardware, but it would be a lot more motivating if I didn’t have to! Thanks! ---

welcome @jbroxson Check out this hot thread which I invite you to discuss at: @DustinWoods has actually created a GPIO board that apparently opens up a whole new set of gpio pins separate from the fpc header. > [@Designing a Ext.
