This is the resistance at two temperature points. The first point (25%) is where the “normal” resistance is taken. The table below the values is what the resistance is a the second point.

I added that to my order. Looking on Digikey, they have B0/50, B25/50, B25/75, B25/85, B25/100. Do you know what that means?

How critical is the B value, or what range can I accept? Currently I am looking on Mouser and I don't see that specific value. Is there a specific or recommended battery pack? I'm just using an 18650 from a local surplus store. I plan to do a number of experiments with various temperature monitoring solutions with self-logging or using another pocket beagle, etc. I want to document my experiments and post the results somewhere, perhaps my github. I also want to have something on the Debian side to gracefully shut the board down when the battery gets low. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
