Here’s another addition to our growing family of AA battery holders. A holder for four (4) 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.
4 x AA battery packs are best used with development boards with 2.1mm DC jacks and can run with ~4.8V (4 x NiMH) to ~6V (4 x Alkaline). Great for powering boards with a ~4.5-6.5V DC input allowance as you’ll see that range depending on how fresh the batteries are.
DC plug is 5.5mm OD, 2.1mm ID with center-positive polarity.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
