The Pimoroni Inky Impression 4.0" (2025 / Spectra 6) is a 4″ e-ink panel with a resolution of 600×400 pixels showing six Spectra 6 ink colors. Spectra 6 is the current generation of color e-ink: six vivid ink colors with much better saturation than the older 7-color ACeP panels. A full refresh takes roughly 15-30 seconds. Pimoroni's boards are the easiest e-ink hardware to start with: panel and driver electronics come as one unit that plugs straight onto the Pi's GPIO header - no soldering, no separate driver board.
The four side buttons are registered automatically and can trigger events in your scenes - switch scenes, cycle images, anything.
How it works
FrameOS ships a native Nim driver
(pimoroni.inky_impression_4_2025) compiled straight into the binary that runs on your Raspberry Pi - no Python, no
vendor libraries. Each render pass draws your scene into a full-color image,
dithers it to the panel's palette, and pushes the result to the display over SPI.
Setup
- Plug the board onto the Pi's GPIO header.
- Add a frame in the FrameOS backend and select the Pimoroni Inky Impression - 4.0" 2025 edition driver.
- Save & deploy. The panel blinks through a refresh cycle and shows your scene.
Status
🟡 Should work, not yet confirmed on real hardware. The driver shares its controller logic with panels that are confirmed working. If you have this display, report your results with a photo and we'll mark it confirmed.
