Drop a sharp, monochrome dashboard into almost any build with this tiny OLED board. A 0.96-inch 128 × 64-pixel panel sits on a rectangular carrier no bigger than a postage stamp, driven by the ubiquitous SSD1306 controller over a simple two-wire I²C link. Just supply 3 V–5 V, connect SDA and SCL, and start drawing icons, graphs, or scrolling text with off-the-shelf libraries for Arduino, MicroPython, CircuitPython, or MicroBlocks.
