I am making a new sprinkler control system using a Particle Photon and it's associated 4 Relay Shield. I could not find a case for it, so I made one! There are
...Show more some additional holes with labeling for the DB9 connectors I need. I created the case approximately 1/4 inch larger on all sides for wiring and things I could not think of now. : )
Additionally I included mounting tabs for wall mounting.
All LEDs are viewable with the top in place (see holes in the lid). The USB connector is NOT accessible in the case as I do all my programming via WiFi.
Have Fun!
