Battery Holder - 4xAA to Barrel Jack
Connector
PRT-09 835
Description:
This is a simple 4 cell AA battery holder. The 5 inch cable is terminated
with a standard 5.5x2.1mm, center positive barrel jack connector.
The connector mates with the barrel jack on 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.
