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.
Features
- 4.2" EPD display (400x300 pixels)
- 40-pin female header included to boost height for full-size Pis
- Standoffs included to securely attach to your Pi
- Additional pins, including I2C and SPI, broken out
- Inky wHAT pinout
- Compatible with all 40-pin header Raspberry Pi models
- Python library
- Comes fully assembled
Multi-colour EPD displays, like the one on Inky wHAT, 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 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 our installer to get everything set up!
We've also broken out some handy pins including I2C and SPI, on the back of Inky wHAT, letting you connect additional devices like our breakouts and allowing you to show their data right on the display.
Inky wHAT work with any 40-pin version of the Pi, including Pi Zero and Pi Zero W.
Software
Our Python library takes the stress out of displaying text and images on Inky wHAT, and we've put together a few examples to show off Inky wHAT's capabilities. We've put together a one-line-installer for the Python library too, to make installation a little more straightforward.
Notes
- Pro-tip: you can treat the three-colour displays as black and white - InkyPHAT("black") - and they'll refresh as quickly as a black and white display, in just a couple of seconds
- The Inky wHAT display is made from glass so it's pretty fragile. Be careful not to drop it or press too hard on it, or it will crack. When fitting the wHAT, grip at the edges of the board rather than pressing on top.
- Overall dimensions: 91x77x8.5mm (WxHxD, depth includes header and display)
- Display usable area dimensions: 84.8x63.6mm (WxH), 4.2" diagonal
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- pHAT
- A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
