The Adafruit USB Isolator is becoming more popular now that so many people are using USB-based oscilloscopes and logic analysers. The problem this board solves occurs when the ground of the device you are testing and the testing device itself are connected. This handy little board isolates the ground between the two. It allows for low-speed and full-speed connections. Sorry, no high-speed here, but that’s OK for so many other applications.
Eliminate the dangers of back-fed power, background noise, floating grounds, or other hazards of tinkering around with USB-based testing instruments. Just remember the Adafruit USB Isolator is only for 5 V power and 3.3 V logic USB devices!
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.
