Assuming I'm not currently hooking up any sensors or other components, what is the average current draw for both the Uno and the Due?
I need to be able to calculate how long a LiPo battery is going to last me so I can get the one with the smallest form factor, but I can't do this until I figure out what each board uses.
For the Uno, about 50mA. I don't know what the Due needs.
But perhaps there is another solution.
If you want, you can run an Arduino on a Lipo cell for years (with a barebone ATmega chip that is in sleep almost all the time).
Can you take a look at the Adafruit.com website. Look for wearables.
Do you really need 5V ?
If not, you can run some Arduino boards directly with the Lipo voltage.
Do you know the energy-harvesting-chips ?
There are many posibilities, but it depends on what you want to do with the Arduino.
I agree, you can design with the Arduino, but then cut back to just the Atmel chip itself and use sleep mode.
Due: 130mA
Thank you all for the info. No, I haven't heard of energy harvesting chips. Got any details on those? I'll google that while I wait for an answer but would be interested in anything you have to add.
I think every major chip manufacturer has them.
They are hard to compare, one chip is for batteries, other chips for solar and other chips collect energy from radio waves. Some chips collect energy from everything, but are totally different from others that do the same.
