USB C to DC barrel jacks…with USB PD voltage selection!

We got a few samples of these very nifty USB C cables – there’s a Type C plug on one end and a DC 2.5mm/2.1mm on the other. On the plug is etched a voltage and current range. inside is a USB C PD chip that negotiates to try and get the selected voltage and current out of a USB C power plug with Power Delivery management, and it works! we got 9V, 12V, 15V and 20V cables and tested it with our 3A test load and the cables had almost no drop. these could be super handy for getting significant power from USB C without having to do the noodling of programming or configuring a PD chip. coming soon to the adafruit shop! – video.


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.
