Now that I am more familiar with the vagaries of the major components I have the architecture planned out, but who knows if I can make it work. I can already see that it is going to take quite a bit of experimentation with the many parameters to get the power budget down.
It’s getting quite complicated already as you can see from my back-of-the-envelope sketch. Clearly this isn’t going to come together in a hurry. Perhaps the most useful thing is that I have figured out what all the LEDs are for 😀
