I was literally just have a SOM moment and now this! Wonderful! Please yes! There is no protocol here afaik, but one could be built around the ADC and the USB functionality so that one could say, configure a 20 bit digital bus, or configure the output path to an ethernet port. This an excellent start and even in qty 1, the NGFF connector is $1. This will allow dev boards and the chips they support to become more full featured.
