Waveshare 7.3 inch 7 Color E-Ink Display 800×480 E-Paper with HAT is an ACeP 7-color reflective e-paper HAT designed for Raspberry Pi and other SPI-capable controllers that need richer color output than a monochrome display while still keeping the low-power benefits of e-paper. With its 800 x 480 resolution, 7-color display, and paper-like readability under ambient light, it is a strong fit for electronic shelf labels, smart price tags, conference badges, asset tags, and low-power color information panels.
Compared with a raw color e-paper panel, this version is much easier to prototype with because it already includes the Raspberry Pi 40PIN GPIO HAT format, SPI control interface, and onboard voltage translation for 3.3V / 5V MCUs. Waveshare provides the official 7.3 inch e-Paper HAT (F) wiki, the display specification PDF, and the official demo code package for development reference.
Features
- 7.3 inch ACeP 7-color e-paper HAT for Raspberry Pi and other supported host platforms.
- 800 x 480 resolution for color labels, signage, badges, and embedded information displays.
- 7-color display support for richer visual communication than monochrome or tri-color e-paper.
- Standard Raspberry Pi 40PIN GPIO header for straightforward hardware integration.
- SPI interface for use with Raspberry Pi, Jetson Nano, Arduino, STM32, and other controllers.
- No backlight, with the last image retained after power-off.
- Ultra-low power consumption, with power mainly required during refresh.

Applications
- Electronic shelf labels with richer color coding and stronger visual hierarchy.
- Smart price tags that need more expressive color presentation than black-and-white e-paper.
- Conference badges and name tags with colorful branding, role marking, or category grouping.
- Asset and equipment tags with clearer status or category differentiation.
- Low-power color information panels for embedded terminals and static signage.

Other Content
This SKU is a ready-to-develop 7-color HAT, so it is easier to evaluate than a raw color e-paper panel. It is especially useful when you want color without the constant power draw of a conventional TFT or OLED screen.
The combination of ACeP 7-color display, Raspberry Pi HAT compatibility, and ultra-low standby power makes it a strong option for retail labels, product displays, badges, industrial labeling, and embedded color dashboards that update occasionally rather than continuously.

FAQ
Is this a raw display or a HAT board?
This SKU is a 7.3 inch e-Paper HAT (F) with a Raspberry Pi-oriented HAT format, so it is easier to prototype with than a raw panel.
What makes this model different from monochrome e-paper displays?
It supports a 7-color ACeP display effect, which is better for color-coded labels, signage, badges, and information layouts.
Which controllers can it work with?
Waveshare documents use with Raspberry Pi, Jetson Nano, Arduino, and STM32 through the SPI interface.
What kinds of projects is it best for?
It is a strong fit for price tags, shelf labels, conference badges, asset tags, and low-power color information panels.
