The Pixelduino is a tiny Arduino-compatible microcontroller with a full color 1.5″ OLED display + MicroSD built-in!
About this project
The Pixelduino is an Arduino-compatible microcontroller that features a 1.5″ 128×128 pixel color OLED screen and a MicroSD slot!
There are all sorts of things you can do with a device like this. You can create wearables like a watch, bracelet, pendant, or buckle that displays color images, attach sensors and display data in text or visual form, display debug information, create a graphics user interface, or even make simple retro games.

The display on the Pixelduino is compatible with Adafruit’s GFX library. This library provides functions for blitting images, drawing primitives like lines and circles, and even includes basic bitmapped font support.
The theoretical maximum speed of this display when streaming from the SD card and refreshing the entire screen is ~10 fps. This is based on the speed of the SPI bus and the amount of data that needs to be pushed around.
