4inch E Ink Spectra 6 (E6) Full Color E-Paper Display, Compatible with Raspberry Pi 5/4B/3B/Zero/Zero W/Zero 2W/Pico/Pico W/Pico WH, Jetson Nano and RDK X3, with HAT+ Standard Driver Board

Build low-power visual interfaces with a 4-inch full-color E-paper display. This Generic Brand display uses E Ink Spectra 6 (E6) technology to create full-color images through six-color blending based on primary colors. It is designed for projects that need readable, persistent content without the continuous power draw of a conventional backlit screen.

Designed for development boards

The included HAT+ standard driver board supports a broad range of popular single-board computers and microcontroller platforms, including Raspberry Pi 5, Raspberry Pi 4B, Raspberry Pi 3B, Raspberry Pi Zero, Zero W, Zero 2W, Pico, Pico W, and Pico WH. Compatibility also includes Jetson Nano, Jetson Orin Nano, and RDK X3.

Persistent, low-power display behavior

Because the panel has no backlight, it can continue showing the last refreshed content for a long time after power is disconnected. Electrical power is mainly needed when refreshing the image, making the display useful for dashboards, signage, status panels, labels, schedules, data visualization, and embedded prototypes where energy efficiency matters.

Color and image performance

E Ink Spectra 6 provides high contrast and high color saturation compared with conventional monochrome e-paper. The panel does not display only six colors; its six-color blending process combines primary colors to produce full-color images. As with other reflective e-paper technologies, color appearance and refresh performance may differ from true emissive full-color displays.

Development support

Official Wiki resources are available to assist with hardware connection, software setup, and project development. Confirm the required software, interface configuration, and board-specific support before deployment.

Typical applications

• Low-power information dashboards
• Color status displays and monitoring panels
• Electronic labels and signage prototypes
• Schedules, notifications, and data visualization
• Embedded Raspberry Pi, Jetson, and RDK X3 projects

Compatibility note: This listing identifies supported host platforms based on the supplied product information. Additional cables, power supplies, mounting hardware, and software may be required depending on the selected development board and application.

Frequently Asked Questions

Does this display show more than six colors?

Yes. E Ink Spectra 6 uses six-color blending based on primary colors to produce full-color images rather than limiting output to six solid colors.

Does the screen need continuous power to keep an image visible?

No. The no-backlight e-paper panel can retain the last refreshed content for an extended period after power is removed. Power is primarily needed during refresh.

Which Raspberry Pi boards are supported?

Supported models include Raspberry Pi 5, 4B, 3B, Zero, Zero W, Zero 2W, Pico, Pico W, and Pico WH.

Can it be used with Jetson or RDK X3 platforms?

Yes. The supplied compatibility information includes Jetson Nano, Jetson Orin Nano, and RDK X3.
