A20-Olinuxino-MICRO + LiPo battery (how to generate 5 V for GPIO pin)

[felipegn]

Hello guys.

https://www.olimex.com/wiki/A20-OLinuXino-MICRO#Power_supply_and_consumption

I read in the above website that "Step-up converter provide 5V for the USB peripherials too". Does this mean that when I power my Olinuxino with LiPo battery (3,7V) it automatically transforms this tension into 5V for USB periphericals when the other things are powered by 3,7V?

If the answer is Yes, I also would like to know if the pin +5V in GPIOs is powered with +5V when I power Olinuxino with a battery.

Thank you!

Best regards.

Yes to both cases.

If you look at the schematic there is a step up converter (U16) that takes the battery voltage and generates 5V and this is present on all of the 5V connections.
