CR2016 Lithium Coin Cell Battery

This is a handy little non-rechargeable CR2016 Lithium Coin Cell Battery!

Sitting at 20mm diameter and is 1.6mm thick it’s small but packs a punch with a nominal voltage output of 3V and a capacity of 90mAh. For other drain rates the capacity may be reduced, check the datasheet! Note that these are often “stacked” to make a 6V CR2032-sized pack of batteries.

In stock and shipping now!

CR2450 Lithium Coin Cell Battery

This is a super beefy non-rechargeable CR2450 Lithium Coin Cell Battery!

Coming in at a 24.5mm diameter and 5mm thickness this battery kicks major butt with a nominal voltage of 3V and a capactiy of 610mAh! For other drain rates the capacity may be reduced, check the datasheet!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
