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

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

COG was asking about the voltage levels. I believe Vih (minimum V
received as HIGH) is 2V and Vil (maximum V received as LOW) is 0.8V,
while Vol = 2.9V and Voh = 0.4V.

Hi Przemek: Thanks for the helpful response with the link to the pdf document.
Hi cmbaker3: Thank you also for the additional advice on what the logic levels can be affected by.
I want to give input to beaglebone black. But my hardware (From which I am giving input to beaglebone) Toggles between 0.5V and 3.3V. My question is till what voltage beaglebone will take it as logic 0
