NEW PRODUCTS – Battery Holder with On/Off Switch, JST, and Belt Clip: 3 x AAA and 3 x AA
NEW PRODUCTS – Battery Holder with On/Off Switch, JST, and Belt Clip: 3 x AAA and 3 x AA
These battery holders connect 3 AAA and 3 AA batteries together in series for powering all kinds of projects. We spec’d these out because the boxes are slim, and 3 AAAs or AAs add up to about 3.3-4.5V, a very similar range to Lithium Ion/polymer (Li-Ion) batteries, plus they each have a nifty on-off switch. That makes them ideal for use with 3.3V projects that have a 2-pin JST connector meant for one of our Li-Ion/Poly batteries. (Of course, you can’t recharge them like Li-Ion/Polys, so don’t try to plug these into one of our Li-Ion/Poly charger boards!) They also feature an ergonomic belt clip for taking your power on the go!
They respectively fit any standard AAA and AA battery. When using rechargeable NiMH the output voltage will range from about 3.7V with charged batteries to 2.7V at the end of life with a nominal voltage of 3.6V. When using alkalines, the output will range from 4.6V with new batteries to 3.3V at the end of life with a nominal voltage of about 4.5V.
The polarity matches that of our 2-pin JST cable and Li-Ion/Poly batteries. They each use a genuine JST connector so they wont ‘catch and tear’ in JST connectors.
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.
