Here it is. Order placed with JLCPCB on Tuesday, arrived Monday a week later. Including both manufacture and shipping from China. Can't complain, although the boards (£2) cost almost 10 times as much as the carriage (£18).
I can't see anything wrong at this stage (yet?).
Hmm, the relay doesn't look 100% right.
I can sort of jiggle the pins a bit but I left this to The Stupid Fat Bloke, who got the coil and contacts swapped over. Besides, it's actually a 5V relay and the output of the Pi is driven by a 3.3V rail. We will fix that later....
There we go. It certainly looks all right.
But now let's try it and see if it actually works...
