Simply apply power to this OLED dev kit to get it up and running. This kit includes a yellow 1.54" OLED display, a breakout board, and a Seeeduino all connected and loaded with demo-code that displays text and images so all you have to do is plug the included micro-USB into a power supply.
The included 128x64 Yellow Graphic OLED display is high contrast and has a super-wide viewing angle. The OLED breakout board handles boosting the input 3.3v up to power the panel, so no higher voltage input is required. The kit ships with the display mounted on the breakout board.
