Inky wHAT (ePaper/E Ink®/EPD) - Red/Yellow/Black/White

Pimoroni PIM785 - Inky wHAT is a large 4.2" (400x300 pixel) E Ink® display for your Raspberry Pi. Now available in a four colour version (red / yellow / black / white).

Inky wHAT is a bigger version of popular Inky pHAT. The larger high-contrast display opens up many more possibilities, with significantly more space to display information. Like Inky pHAT, it's ideal for displaying simple graphics and crisply-rendered text and, because it's like paper, it's readable in bright sunlight.

Use Inky wHAT as a detailed weather display, as a calendar, for daily news reports, to list household chores, or you could even use it as a tiny DIY e-reader to read your e-books. 

Getting Started with Inky wHAT tutorial is a great starting point for getting acquainted with the joys of e-paper!

Now in glorious four-colour ✨

Advances in e-paper technology mean we can now use a fancy new four colour display on Inky wHAT. You no longer need to choose between yellow and red, you can have both!

Photos showing the new display are coming soon. Be sure to enter your email in the stock notification box if you'd like to know when the new boards are available to order! ➡

Features

• 2.13" EPD display (250x122 pixels)
• Inky pHAT pinout
• Compatible with all 40-pin header Raspberry Pi models
• Python library
• Comes fully assembled

Multi-colour EPD displays, like the ones on Inky pHAT, use ingenious 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 lights. It takes approximately 20 seconds to refresh the display, with a typical 8mA current draw during refreshes. The black/white display can be refreshed much more quickly, in just a second or two.

Everything comes fully-assembled, and there's no soldering required! The display is securely stuck down to the Inky pHAT PCB and connected via a ribbon cable. Just pop Inky pHAT on your Pi and run our installer to get everything set up!

It'll work with any 40-pin version of the Pi, including Pi Zero and Pi Zero W.
