Maximum Voltage for Beaglebone Black

Hi all,

What is the maximum recommended voltage for the BBB? I’ve seen the minimum is 4.1v but I haven’t seen any mention of a maximum.
I have a 6 volt (4xAA batteries) battery pack and I want to wire that to a barrel jack connector to power the BBB. I think right now the voltage is ~5.7v. Is this safe?

Thanks,
Andrew

Do you mean input voltage? Have you looked at the SRM?

Maximum is 5.2V. 5.7V is not safe as it will blow up the 5V switch that controls the USB host voltage.
