Put your Snap! cassette on and sing along to “I got the power!” with this super useful power supply adapter where you can easily change the voltage with a snap of your fingers. On the front is a potentiometer knob and a LED 7-segment digital display. Twist the knob and look at the output voltage to range from 3 to 12V DC. It’s kinda like a benchtop supply you can take with you anywhere. Or if you don’t wanna take it anywhere, it has six mounting holes for a more permanent power supply spot.
These incredibly small and slim surface-mount NeoPixel LEDs are an easy way to add a lot of very tiny (but bright!) colorful dots to your project. They are just 3.2mm x 1.0mm x 1.48mm and can be soldered in a few different ways: flat against a PCB, reverse mount using the top pads and a cutout in the PCB, and right angle. As they are pretty darn tiny, they will be difficult to hand solder. SMT techniques with solder paste and hot air will work best here.

This tiny coin cell battery holder is ideal for small portable or wearable projects. It holds one 20mm coin cell (also known as CR2032) in series to generate 3V nominal. 20mm coin cells are popular as they are used in keychain lights and remotes, so they are easy to get and fairly low cost. They tend to have about 220mAh capacity.
Measure the invisible magnetic fields that surround us, with this wide-range magnetometer. The MLX90393 is a wide range magnetic field sensor, that can measure 16-bits in ranges from ±5mT up to ±50mT in all 3 axes.
Easy e-paper finally comes to microcontrollers, with this breakout that’s designed to make it a breeze to add a tri-color eInk display. Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!

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.
