Inky wHAT is a 400x300 pixel electronic paper (ePaper/eInk/EPD) display for Raspberry Pi, a larger version of the popular Inky pHAT display, with more than 5x the number of pixels, and available in three color schemes - red/black/white, yellow/black/white, and black/white.
The larger display opens up many more possibilities, with significantly more space to display information. Like Inky pHAT, the display is crisp and 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.
Multi-color EPD displays, like the one on Inky wHAT, use ingenious electrophoresis to pull colored particles up and down on the display. The colored particles reflect light, unlike most display types, meaning that they're visible under bright lights. It takes approximately 25 seconds to refresh the display.
Everything comes fully-assembled, and there's no soldering required! The display is securely stuck down to the Inky wHAT PCB and connected via a ribbon cable. Just pop Inky wHAT on your Pi and run the installer to get everything set up!
There are also handy pins including I2C and SPI, on the back of Inky wHAT, letting you connect additional devices like breakouts and allowing you to show their data right on the display.
Inky wHAT works with any 40-pin version of the Pi, including Pi Zero and Pi Zero W.
The Python library takes the stress out of displaying text and images on Inky wHAT, and there are a few examples to show off Inky wHAT's capabilities. There's a one-line-installer for the Python library too, to make installation a little more straightforward.
