As technology changes and adapts, so does Adafruit, and speaking of adapting, this adapter has a 2.1mm barrel jack socket and a USB C plug – you could use this to power a USB C device from a common wall adapter.
USB C is the latest industry-standard connector for transmitting data and power. Like Lightning and MagSafe cables, USB C has no up or down orientation. Plug this adapter onto the end of a 2.1mm 5VDC barrel jack, and now it’s a USB C, however, please be aware there’s no protection circuit or Power Delivery negotiation, you really should only be using this with a 5V adapter but if you have the wrong polarity or voltage, you could damage your electronics!
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.
