Bought this for the digispark board to find out that it will not power it. However, it will power an ATTINY85 with fade on a 3mm LED.

No wonder: the digispark board runs from >= 5V. You might use 2*lilypad coin cell boards in series, but have a look at the current requirements of the digispark board. your 2032s will drain rather quickly.

Surely they would. I simply didn't realize they required that much. I assumed since it had a tiny85 that it would run it.

I left the tiny85 with a single led running the fade sketch. It has been going for about 21 hours now and shows no signs of getting dim.

I really like these ATtiny chips.

So after a week of running 24/7, the LED is now dimming (accidental pun). Pretty good for a used battery.
