The AA boost Module is DFrobot's exclusive product. One of its key features is solving the 5V battery power supply problem. As we all know, one AA battery is 1.5V , with two or three you still cannot get 5V. Now with this AA boost module, insert two dry batteries, flip the power switch, and you have a 5V output to power your circuit. Two AA batteries will be enough to reach standard 5V easily and convenient to use, which also provides a more simple supply scheme to Arduino sensors and controllers. This AA boost module integrates with the boost chip TPS61032 from TI that is capable of outputing 5V@1A with input over 1.8V. The only difference between V1 and V2 is changing the output current from 2A to 1A.
