If you google “Beaglebone System reference Manual” it will tell you everything 
you need to know and more.

 

A/D Max input:  1.8V

Logic levels: 3.3V logic

Subject: [beagleboard] BeagleBone Black Input Voltage Range and corresponding 
Logic Levels?

 

Hi:

I would like to know (preferably from a datasheet or similar) the input voltage 
ranges that would equate to a 'logic low' and a 'logic high' for the BBB?

Here is an example of what I am talking about:
See the sub topic Arduino Logic Levels on the page titled 'Logic Levels' 
(https://learn.sparkfun.com/tutorials/logic-levels).

Thanks
COG
