2.13inch E-Ink HAT for Raspberry Pi

This 2.13inch E-Ink display HAT connects to Raspberry Pi boards and Jetson Nano through the standard 40-pin GPIO header. It uses an embedded controller and a 3-wire or 4-wire SPI interface to drive a 212 by 104 pixel panel. The screen shows red, black and white without a backlight and retains its image when power is removed.

Makers building shelf labels

The three-colour e-paper suits projects that need readable updates without constant power, such as price tags or sensor readouts. A full refresh takes 15 seconds, so the panel is not suited to animation or video-rate changes. Buyers who want a backlit display or faster refresh should look at other display technologies.

Check your host board and mounting space

Verify that your Raspberry Pi or Jetson Nano exposes the 40-pin header and can supply 3.3 V or 5 V to the HAT. The module outline measures 65 mm by 30.2 mm with a 23.71 mm by 48.55 mm active area, so confirm clearance inside your enclosure. Solder pads are provided for SPI connection to other controllers such as Arduino or Nucleo boards.

Questions about this item

Does this HAT need a Raspberry Pi with a 40-pin GPIO header to operate?

Yes, it connects through the standard 40-pin GPIO extension header on Raspberry Pi boards and Jetson Nano.

Can I still use the SPI pins for another device while this display is attached?

The board includes preserved solder pads for the SPI interface so you can wire an additional controller such as an Arduino or Nucleo alongside the HAT.

How can I confirm the panel is refreshing correctly after installation?

A full refresh cycle takes about 15 seconds and the screen should show red, black and white content without a backlight.
