Thanks Ray. Just one more quick question please:
What is the spare current (after you subtract what’s needed for the OSPi) that I can draw from the +5V regulator LM2596S for my external circuitry?
I have a hefty 24VAC 3A (75VA) transformer and am using only 6 regular sprinkler valves so there’s plenty of capacity there. From the LM2596 spec, it seems like it should be able to do 3A but wanted to confirm.
Your customer support is dearly appreciated!!
