Hey, I have a few questions about the laptop housing.
- How does one connect it to power?
standard DC jack, anywhere between 7 and 19v.
Can it be powered over USB
powered no, charged, yes. current limit on the OTG port.
or does it require a specific AC adapter?
no. min 4A is best, but if you're prepared to reprogram the STM32F072 yourself you could get away with less
I have a portable solar array with a battery pack that can charge portable devices over USB, and I'm trying to work out whether or not I'll be able to power the laptop from it.
- What's the average power draw of the laptop housing with an
EOMA68-A20 card?
don't know. max is 15W
If my rough calculations are correct, I think it should be around 6.25-8.3 W?
mmm LCD is around 4. if you play an audio file at full volume it'll take another 3W.
(Looking into CPU power specs has given me quite a bit of respect for Intel's engineers; it's amazing that modern laptops are able to do so much with so little power.)
yeah... :)
