Powering a Zero and Scroll pHAT with a battery
I've tested it, and it lasted about 11½ hours on the Anker slim battery. Not bad!
View ArticlePowering a Zero and Scroll pHAT with a battery
At most the Scroll pHAT should draw about 180 to 200mA. This is full brightness with all LEDs lit. At 50% brightness it's around 70-80mA. At 25% brightness it's around 40mA. 100% - 200mA 50% - 80mA...

I've successfully driven a Unipolar stepper motor ( 28BYJ-48 ) from Explorer HAT and documented it in this gist: https://gist.github.com/Gadgetoid/f26f088463c431b40aa3

Thanks for quick response , I have checked out the link and it all seems straight forward. Is there any reason why the four 5v outputs can't be used instead of the motor outputs? Steve

That figures. 3350 mAh on the battery / 11.5 hrs = 291.3 mA of current. The Pi Zero draws about 100 mA, it says here, which leaves just under 200mA for the Scroll pHAT.

What sort of savings can I expect by disabling non-essential parts of Raspbian and/or the Pi itself? And will it be worth it? I've not spent any time looking into this yet, but I understand you can...

Tho' batteries aren't 100% efficient, so you're probably looking at more like (3350 * 0.7) / 11.5 - 100 for about 100mA for the Scroll pHAT as Phil says.

I read that the camera ribbon can also be used just fine and that made me question can the camera hdmi extension cable be used to offer hdmi input to the display? Would be useful for the RPi zero?

I don't believe there's any reason why not. However the 5v outputs pull down to ground, so you'll need to supply 5V to the common pin of the stepper, and pull the other connections down in the correct...

Yes, fair enough. They're not all on at full brightness in my application. Still, 11½ hours is pretty good.
