I developed my own relay board for the raspberry pi because I had 9 zones and didn’t want to have to use an opensprinklerpi + expansion just for the one extra zone. I posted the design on github in case anyone else wanted to use it: https://github.com/nhorvath/sprinklers_pi/tree/master/hardware/Sprinkler%20Controller
Nice design and I’m impressed you went all the way to making the board yourself.
I hadn’t checked up on Fritzing in a years and didn’t know it can do PCB layout now, very cool.
Just for grins I uploaded the Gerbers to OSHPark to get a quote. $60 for 3 boards.
