Inky Impression 4.0"

The Pimoroni Inky Impression E Ink® Display adds a vibrant, low-power colour E Ink screen to your Raspberry Pi, complete with onboard buttons and Qw/ST connectivity for creating eye-catching dashboards, signs, status displays, and interactive projects. The Pimoroni Inky Impression E Ink® displays are super crisp, low power and look great from a variety of viewing angles. They have high pixel density and bright vivid colours, perfect for showing off gorgeous dithered images. They also include: The appropriate hardware to attach to your Raspberry Pi computer and fix it securely in place. If your Pi has a 40 pin header attached, you won't need to do any soldering. Four rear mounted buttons, for interacting with the screen. Qwiic/STEMMA QT connectors, so you can easily connect up breakouts and other I2C devices. Inky Impression is available in 4.0" (600 x 400), 7.3” (800 x 480 pixel) and 13.3” (1600 x 1200 pixel) sizes. Tell me about EInk® Multi-colour EPD displays use electrophoresis to pull coloured particles up and down on the display. The coloured particles reflect light, unlike most display types, meaning that they're visible under bright light. They don’t use a backlight like LCDs do, so they’re easy on the eyes and don’t introduce unwanted light into your environment. Electronic paper displays only consume power whilst they're refreshing, so they're a great choice for projects like home automation dashboards and electronic photo frames that need to be always on. They take a little while to refresh, so are best suited to projects that don't require constant screen updates. Spectra 6® Technology The six colour display panels that we now use on Inky Impression bring a number of improvements over previous panels - notably a shorter refresh time and more saturated colours. They also come in an extended range of sizes, so we’ve been able to make a huge 13.3” (1600 x 1200 pixel) version - that’s almost A4 size! Features 4.0" (600 x 400), 7.3” (800 x 480 pixel) or 13.3” (1600 x 1200 pixel) ePaper display E Ink Spectra 6® technology Ultra wide viewing angles Ultra low power consumption Four rear mounted buttons M2 mounting holes at the corners 40-pin extension header included to boost height for full-size Raspberry Pi. Standoffs included to securely attach to your Pi Qw/ST (Qwiic/STEMMA QT) connectors for adding breakouts Expansion header for adding other hardware Compatible with all 40-pin header Raspberry Pi computers, including Zero variants. Python library Comes fully assembled, with no soldering required (as long as your Pi has a 40-pin header attached). The display is securely stuck down to the Inky Impression PCB and connected via a ribbon cable, and it comes with mounting hardware to attach your Raspberry Pi securely in place. Just pop Inky Impression on your Pi and run our installer to get everything set up! Software The Python library takes the stress out of displaying text and images on Inky Impression.

Be careful not to drop it or press too hard on it, or it will crack. When fitting it to your Pi, grip at the edges of the board rather than pressing on top of the screen. This is not a touchscreen! This is the manufacturer's core refresh time at 25°C - 50°C - cooler temperatures may make the refresh take longer. It also takes a few seconds for the display to report a ready state and for data to be sent from the Raspberry Pi over SPI. You can expect a complete 'real world' refresh cycle to take between 20 and 35 seconds, depending the speed of your Pi and what variety of panel you have. Revision History Inky Impressions made from November 2025 onwards have rear mounted buttons instead of side mounted ones. This should hopefully help resolve issues with the buttons getting knocked off during transit! Package Contents 1x Inky Impression 4.0" 1x Set of 4 extended Pi standoffs 1x Double row header strip
