Brain Cog Power Draw

Each of eight cogs draw power
when in use

From time to time we will review the power consumption aspects of the Brain. We need to know the aspects of all power draw in the Brain as things are leading towards the development of battery operation for mobile robots (as one app). Dr. Braino has pointed out, as seen in the Propeller Specification sheet, a cog draws something on the order of 1 uA per Mkz per core and inactive cores are 0 uA. So every time a cog is turned on, it will draw a small amount of extra power. It may not seem like much, but multiplied by hundreds, or many thousand of cogs, it will add up and every milli-amp is significant.
