Hello, is it possible to turn off the VDD_5V pin or the SYS_5V pin?
Why would you want to do that ?
I wanted to power an Arduino and I didn’t want to use a relay.
Yes, you can turn those off by unplugging the power supply.
Technically speaking, what you’re asking I do think is possible. When using a battery, the beaglebone will still continue running after the 5VDC input is removed. However, since the battery is only 3.7v nominal. you’ll no longer have a 5volt rail to power the USB. That’s at minimum. I’m not sure whatever other effects you’ll encounter here, but the beaglebone will continue to run until shutdown, or ( not recommended ) the battery runs out of usable power.
