That’s a microcontroller, 4 Watt step-up power supply, accelerometer, LED driver, and switched output stage. Oh, and bonus connectors. Ended up with a design that looks like:
Three boards, to go on top of each other. There’s links between the boards that are hard to move around. There’s components on each board that can’t be moved. Getting everything to fit together was complicated. Didn’t I say I was going to do something easy this time?
It should all fit, and it should all work, but frankly, I’m just going to have to try it. Now, squeezing that much power into that small a space might mean that it all melts, but we’ll have to see…
