4.01" 7-Colour ePaper HAT

The Pimoroni Inky Impression is a 4.01 inch E Ink Gallery Palette display offering seven colours including black, white, red, green, blue, yellow and orange. It connects via the 40-pin GPIO header on any compatible Raspberry Pi model. The board arrives fully assembled with a female header and standoffs for secure mounting. It suits makers adding low-power signage or dashboard projects.

Check Pi header and refresh needs

Verify your Raspberry Pi has a standard 40-pin header; earlier 26-pin models are not compatible. The panel uses ACeP technology which refreshes slowly, so it is unsuitable for video or rapid animation. Ensure the ambient temperature is near room level for best colour vibrancy. Handle the glass screen by the board edges only to avoid cracking the fragile display.

Fits Pi builds with I2C expansion

The HAT sits directly on the Pi GPIO pins and adds minimal bulk at 97 by 69 millimetres overall. A usable area of 86 by 54 millimetres provides 640 by 400 pixel resolution at 0.135 millimetre dot pitch. Four side-mounted buttons stay accessible even when wall mounted. Broken-out I2C pins allow extra sensors without soldering, while ultra-low power draw suits battery deployments.
