Here’s another addition to our growing family of AA battery holders. A holder for three (3) AA batteries! It’s got an 8″ long power cable with a 2.1mm DC jack at the end, and, oh yes, it’s in classy Adafruit black.
This battery holder connects 3 AA batteries together for powering all kinds of projects. Three AA’s add up to about 3.6-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries. That makes them ideal for use with 3.3V projects. (Of course, you can’t recharge them like Li-Ion/Polys, so don’t try to plug this into one of our Li-Ion/Poly charger boards!)
Power cable is 200mm long with a DC jack with 2.1mm ID with center-positive polarity.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
