Adafruit FeatherWing OLED 128×64 Display with Buttons: High-Contrast UI Expansion for Feather Boards
The Adafruit FeatherWing OLED 128×64 is a versatile add-on board that brings a crisp, high-contrast 128×64 monochrome OLED display and three user buttons to any Feather main board. Measuring just 1.3″ diagonal, this OLED screen delivers excellent readability thanks to self-illuminating pixels that require no backlight, reducing power consumption while providing outstanding sharpness. Fully compatible with Feather Stacking or Female Headers, it stacks neatly on top of your Feather board for a compact design. Equipped with three tactile buttons (A, B, C) and a reset button, it enables you to add a simple user interface to your project. For users upgrading from the 128×32 OLED FeatherWing, this version offers the same pin compatibility but uses the SH1107 OLED driver, requiring updated code. Ideal for IoT devices, data monitors, and handheld projects, this FeatherWing is a powerful display and input solution.
