Double AA Battery Booster Module

The Double AA Battery Booster module provides a convenient way to power your 5 volt projects from just two AA batteries.

Regular AA batteries provide only 1.5 volts each and rechargeables provide only 1.2. This handy module steps up the voltage from the two AA batteries and boosts it to a steady 5V supply to power your projects.

This module is barely larger than the two AA batteries it requires and is easily attached to your robot project with the three mounting holes. There is an on and off switch for additional convenience. A GS1662 high efficiency step-up DC/DC converter chip preforms the power boosting operation. It can support up two 2A of current and operates at 90% efficiency.

This battery boost module is great for smaller robots that can't be weighed down by too many bulky batteries.
