Waveshare 7.5 inch E-Ink Display 800×480 E-Paper with Hat is a 7.5 inch black-and-white e-paper HAT designed for Raspberry Pi and other SPI-compatible controller platforms. It combines an 800 x 480 e-paper panel with a standard 40PIN GPIO HAT layout, making it a strong choice for low-power display projects that need a paper-like viewing experience without a backlight.

This display features very low power consumption, keeps the image visible even after power-off, and works especially well for price tags, shelf labels, conference badges, equipment tags, industrial instruments, low-power dashboards, and embedded information displays. It can also be used with Jetson Nano, RDK X3, STM32, Arduino, and other SPI hosts.

Features

• 7.5 inch e-paper display with 800 x 480 resolution.
• Black and white paper-like display with 4 grayscale levels.
• Ultra-low power consumption and image retention after power-off.
• Standard Raspberry Pi 40PIN GPIO header for direct HAT-style integration.
• SPI interface for Raspberry Pi, Jetson Nano, STM32, Arduino, and other controller boards.
• Wide viewing angle over 170 degrees with ambient-light readability.
• No backlight required, suitable for long-term static display applications.

Other Content

Broad controller support
This e-paper HAT can be connected directly to Raspberry Pi series boards through the 40PIN GPIO header, and it can also work with Jetson Nano, RDK X3, STM32, Arduino, and other SPI controller boards.

Paper-like display behavior
E-paper reflects ambient light instead of emitting light. That makes it easier to read in bright environments and much better for low-power, always-visible display projects than a conventional LCD.

Interface reference
The main control pins are VCC, GND, DIN, CLK, CS, DC, RST, BUSY, and PWR, which makes it easy to integrate into existing SPI-based embedded systems.

FAQ

Does this display need continuous power to keep the image visible?

No. E-paper keeps the displayed image after power-off, which is one of the biggest advantages for low-power projects.

Can it be used with boards other than Raspberry Pi?

Yes. Besides Raspberry Pi, it can also work with Jetson Nano, RDK X3, STM32, Arduino, and other SPI-based controller boards.

What is it best used for?

It is especially suitable for price tags, shelf labels, conference badges, asset tags, industrial instruments, and low-power information displays.

Does it have a backlight?

No. It is a reflective e-paper display, so it works by reflecting ambient light like printed paper.
