Grab a copy of the Device Characteristics, SPRS717, for the AM335x. Chapter 5 has the electrical parameters. You can chase pins from the ZCZ ball to the section of table 5.7 that looks at that pin. A short and incorrect answer is that logic 0 is less than .8VDC and a logic 1 is greater than

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' (
