Full-Colour ePaper Display HAT+
By Andrew Gregory. Posted
Making use of the same Spectra 6 colour e-ink technology as the Inky Impression range, this looks very similar to the latter’s 4-inch model, albeit with a slightly smaller footprint as it lacks the top and bottom bezels.
There’s a (more compact) nine-pin breakout header on the rear of the board, too, but sadly no user buttons. The integral female GPIO header is tall, which is ideal for a full-size Raspberry Pi, securing it with supplied metal standoffs, but a Zero model won’t sit flush to the rear.
As you’d expect, performance-wise the Spectra 6 screen is very similar to the one on the Inky Impression: crisp with vivid colours and a typical refresh time of around 20 seconds.
As with the 2.13 inch Waveshare HAT, the online documentation is in need of an update, but we can confirm the screen works in Raspberry Pi OS Trixie. There are C and Python libraries and a demo to use as a guide for your own programs.
Verdict
A quality colour e-ink screen that matches Raspberry Pi’s size.
Available from Waveshare and The Pi Hut (£62/$85)
