Love the boards from OshPark, they always come through just great and they're really easy to import if you're using KiCad.... if only I hadn't made a mistake...

Yes, I forgot to actually wire the SSR pin to anything is the schematic, so bodge wire it will be which is a real shame.

Its got a few extra pins for breakout and an I2C connector, plus i've given it a pin header both the S3-Zero and TTDisplay board so either can be used.

TTDisplay:

S3-Zero:

Doing a quick bit of coding to update the pins and running it through a test, it did appear to work pretty well and everythings wired up correctly, but its really going to annoy me having to put a bodge wire in.
