Starting to think about what I'm going to hang off that "front panel" connector.
Current WIP schematic has an indicator LED for each trigger in/out channel (which will eventually have a pulse-stretched activity LED), direction for each of the bidir ports, an LCD that will eventually display IP/MAC address and other config settings, and power/reset buttons.
Still have to figure out all of the logistics of how to go from bare board to pretty front panel (light pipes, display bezels, etc). I've never had a project get that "done" before!
