Pixel 2.0 is tiny OLED screen
The Pixel 2.0 is a tiny OLED screen for your wearable Arduino pleasure

The tiny Pixel 2.0 is basically an Arduino board wedded to a tiny 1.5″ 128×128 color OLED screen. This means you can stick it inside a wearable and address the screen directly from the Arduino board, an improvement on current “solder the screen to the Arduino and hope it works” world of DIY electronics. This teeny-weeny board costs $75 on Kickstarter and should ship in June...
