Particle Photon Relay Board

I have often had the need for a Photon controlled relay to turn a circuit on and off. Although there are many offerings in this space, most involve a wall-wart power adapter in addition to being much larger than desired. So... I decided to design a small board to host a Photon, power adapter and relay to meet these needs.

I already know I'll be making it a bit smaller to tuck into tighter spaces, but it has already proven to be handy when this type of need arises.

[updated!] I noticed an error on the input, so I've redesigned the board just a bit. The board now also has 2 inputs that can be analog or digital! Woohoo! The picture is of the new board and it's about 10% smaller and should fit into an outlet box if desired.
