We were testing the power supply options of our new mikroMMB boards. We have already shown you that powering the board with solar panels is a possible option . But using Battery Boost Board you can even power the board with a single AA battery. Although current consumption is higher than we expected, it still can be done. Depending on your application battery lifetime may vary, but don’t use a single battery as a long term power supply option. For longer battery life we still recommend you to use 2 x 1.5V AA batteries connected in series.
