The Waveshare 7.5" (B) e-Paper is a 7.5″ e-ink panel with a resolution of 640×384 pixels showing black, white and red. Panels with an accent ink run a multi-pass refresh that takes roughly 15-30 seconds, so they suit art, calendars and dashboards that update every few minutes rather than every second. Like all e-paper, it keeps the last image with zero power - the frame only wakes up to render.
How it works
FrameOS ships a native Nim driver
(waveshare.EPD_7in5b) 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
- Connect the panel to the Raspberry Pi - plug the HAT onto the GPIO header, or hook up the separate driver board with the bundled ribbon cable.
- Add a frame in the FrameOS backend and select the Waveshare 7.5" (B) 640x384 Black/White/Red driver.
- Save & deploy. The panel blinks through a refresh cycle and shows your scene.
Make sure the letter suffix on your panel's ribbon cable matches the driver - Waveshare reuses product names across revisions. More tips in the Waveshare buying guide.
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.
