Yeah! For the IR it was clear to me. But it will not be powered all the time.
But surprises me that a 32bits faster processor drain less that 8bits slower one. Of course all depends on the manufacturing process. But used to be the other way.
@MLXXXp has got some good ideas on the Zero. Adafruit has the feather with the zero and an sd card built into it. So I’m looking at grabbing one of those and getting it to talk to the screen. Looks like Scott may have done a lot of the heavy lifting.
I’ve got to check into what the cost and supply of the new chip is also.
This is almost certainly going to happen. I need to make some tests on what kind of LED and what strength will be.
If you put a WiFi or Bluetooth module behind the back cover, you may need a different cover anyway, regardless of the size limitations. The current metal cover would likely shield and block the signals, so a different cover material would be required.
