The Great Search: 12V to 5V 2+ Amp buck converter #TheGreatSearch #digikey #adafruit @DigiKey @adafruit
This week (video) we’re working on reviving our old floppy hacking projects by making a development board that will let us connect to various old-school disk drives to either control or emulate them.
These devices used lots of motors and solenoids to spin and eject the discs, so we will need to be able to provide them with a good amount of current.
For 3 1/2″ floppy drives, 5 Volts at 1 Amp or so is not unusual, and we expect larger disk drives may need even more power. For the other motors, we’ll want to have a 12 V power supply input, so we need to convert 12V to 5V, and at these currents, an LDO like the 1117-series will have to dissipate way more heat than we’d be able to get rid of – that’s when a buck converter is a great alternative.
Let’s find a powerful and affordable converter that can provide 2A or more.

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.
