Many times while traveling, I have had the need to debug my firmware on a circuit board. Unfortunately, I was not carrying a power supply. So in turn, I had to wait until I reached my lab before I could power my circuit board to test the new firmware. This new innovative project, the USB Based Variable Power Supply, will solve this issue effectively, affordably, and reliably.
A quality power supply is crucial for anyone who is into computer engineering but most variable power supplies are AC/DC, which are large and very inconvenient to carry while traveling.
VariPower-USB-500A is open source hardware. All hardware design files and firmware source code are released under the GPL v2 license. It’s a great way to get started with 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.
