The 4.2" E-Ink/E-Paper Display (400x300, Monochrome/Grayscale) uses the SSD1683 chipset and connects via a 24-pin FPC connector. It supports 4-level grayscale mode and offers daylight-readable, low-power performance with driver board compatibility.
E-Ink/E-Paper displays make for great low-power displays that are daylight visible and keep their image even when depowered. For folks who want to DIY their own E-Ink setups, this is a 4.2" diagonal Monochrome or 4-level Grayscale eInk / ePaper Bare Display with 400 x 300 pixels.
Chances are you've seen one of those new-fangled 'e-readers' like the Kindle or Nook. They have gigantic electronic paper 'static' displays, which means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!
Please note: this is the bare display element.You need to plug it into a board with a 'standard' 24-pin FPC e-paper connector.We recommend checking out and picking up a matching driver board:
Feather RP2040 ThinkInk- solderless plug-and-play solution with Arduino or CircuitPython support. Definitely the easiest way to get started, and it is what we show in the demo above
Note that you can put this display into a '4-gray' mode, where you get two extra monochromatic shades. It's notofficially supported by the display, but it does kinda work.Check out our guide on dithering for how to get the best output from these panels.
