Battery Holder - 4xAA to Barrel Jack Connector

The Sparkfun Battery Holder with a 4xAA to Barrel Jack Connector is a simple yet effective tool for powering your projects. It holds four AA batteries and features a 12.7cm cable terminated with a standard 5.5x2.1mm, center positive barrel jack connector.

This battery holder is compatible with the Arduino and a range of other products, enabling you to switch your project to battery power with ease. It's an excellent solution for those seeking portability or a wireless setup for their projects.

It's important to note that the average voltage regulator has about 1V of dropout, which can vary significantly. This pack, with regular alkaline batteries, will output approximately 5.5V, causing a standard 5V board to operate at around 4 to 4.5V. The actual voltage will depend on the specific board and processor used with the battery pack. Therefore, it's recommended to refer to the datasheet of your board and processor for precise information.

With its simple design and compatibility, the Sparkfun Battery Holder with a 4xAA to Barrel Jack Connector is a practical accessory for any project. Its unique properties make it a versatile tool that can help bring your innovative ideas to life.
