Powered by the Raspberry Pi Pico 2 W, the Inky Frame 7.3 is a 7.3-inch ePaper display that combines energy efficiency, vivid colors, and multipurpose functionality. With a resolution of 800 × 480 pixels and capability for seven colors, this display is ideal for low-power uses such as static pictures, sensor data displays, and dashboards for home automation.
E Ink technology, which is renowned for using extremely little power, is used in the display. When not in use, it retains graphics and just requires energy for screen refreshes. It is therefore perfect for battery-powered applications, and it has mounting options that work with a variety of layouts.
