AA Boost Module V2

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 outputting 5V@1A with input over 1.8V. The only difference between V1 and V2 is changing the output current from 2A to 1A.
