Hello,

I am estimating battery life for a system that uses your DAQ board. The DAQ specifications list a “Max output current” of 250 mA.

For my power-budget calculations, I would like to inquire about the DAQ board’s current consumption while active. A value at 3.3 V would be ideal, but an estimate at any operating voltage would also be helpful.
