Really tiny Step up boost converter. It works flawlessly.
I arrive well, i have n't used

Sweet little boosters, using them for 1S lipo stuff so I can run 5V devices on them. I'd like to put an oscilloscope on the output to see how noisy they are, but I usually throw on a capacitor anyways.
Small size, perfect for any project.
Small design could not be tested yet
very small product does not take up space and works very well.
very tiny, great miniaturization of the application possible. can make with 1 battery from 3.7V stable 5V. Sizes Elko 2000 uF not forgotten at 5V!
