Tons. This is great to slap in temperature controllers, actuators, control loop things and the like. I would probably use this in lieu of the Pi Automation Hat for things like my greenhouse controller, if I didn't already have the parts for it. It would also be great for making into RS232 driven GPIO boards using a simple protocol. Actually I'd love to see someone develop a daisy-chainable automation IO board using these. Auto-sense the neighbors, assign registers to I/O pins, and make a protocol based on Msgpack or a subset.
