This is a simple 4 cell AA battery holder. The 10cm cable is terminated with a standard 5.5x2.1mm, center positive barrel jack connector. The connector mates with the barrel jack o n the Arduino (among a number of other products) allowing you to easily make your project battery powered. Note: the average voltage regulator has about 1V of dropout (but can vary greatly). This pack, with normal alkaline batteries, will output ~5.5V causing a normal 5V board to run at around 4 to 4.5V. This depends a lot of what board and processor you are using with the battery pack. Please consult yer datasheet. Show more
