While this may appear to be an electronic shuriken, it’s actually a Multifunctional USB Digital Tester!
This handy (pun intended?) tool can measure voltage, current, power, charge time, and other measurements for USB A, Micro B, and USB C! It features a colorful display that pops up when you plug in a power supply. Each click of the button gives you a different display and readout. A long press will reset the data for when it does Coulomb-counting (total power consumption). We like the simple display that comes up first with big Voltage and Current output, but you have lots of options.
There are 4 connectors so you can go from type A to C, type A to A or type C to C.
Works great with laptops, smartphones, tablets, what have you, it’s perfect for testing any USB power setup but this model is a little nicer in that it is also good for USB C with its higher current and voltage capabilities – up to 32V and 5A!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
