The Great Search: 5V eFuse #TheGreatSearch #DigiKey @digikey @Adafruit
(Video) eFuses are a nifty way to protect your electronics from over/under powering – handy for maker electronics AND industrial equipment that needs to keep chugging along no matter what happens to the power supply.
We had someone ask us to design a board that would take 4xAA input and give USB output – one way to do that is with a buck-boost converter (which we already have) but maybe we could get away with a lower-cost and complexity design. Instead we’ll look for an eFuse that will permit no more than about 5.5V and have reverse current, reverse voltage and under/over voltage protection!

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.
