WaveShare 2.66inch E-Paper Display Module 296×152 SPI

SKU CH-8BS1-D5396

A 2.66inch black-and-white e-paper display with 296×152 resolution, SPI interface and 0.3s partial refresh that retains its image without power

  • No backlight retains image without power
  • Ultra-low power draws energy only during refresh
  • SPI interface minimises GPIO pin usage
  • Partial refresh updates screen in 0.3 s
  • 296 × 152 pixel resolution on 2.66 inch display

2.66inch E-Paper Display Module

This 2.66inch E-Paper Display Module is a black and white passive screen with a 296×152 resolution and SPI interface. It operates at 3.3V and targets developers adding persistent readouts to embedded projects.

Development resources and partial refresh

The board ships with C/C++ and MicroPython examples for Raspberry Pi Pico so code can drive the panel immediately. Partial refresh in .3 seconds updates only changed segments, keeping average current draw extremely low.

3.3V logic and pin budget

Verify that your host board provides 3.3V logic levels and enough free GPIO for the SPI lines before ordering. Projects needing colour, greyscale, video-rate animation or a different diagonal will not be served by this module.

Questions about this item

Does the 2.66inch E-Paper display need any periodic maintenance or component replacement?

The module has no backlight and retains the last image without power, so there are no consumable parts or scheduled maintenance tasks.

What is the first limitation that appears during continuous partial refreshes on the 296×152 panel?

Each partial refresh takes 0.3s, so the 0.3s cycle time becomes the throughput ceiling when updating content repeatedly.

How much heat or power does the SPI E-Ink module produce when it runs all day?

Power is only drawn during the brief 0.3s refresh at 3.3V; between updates the display consumes virtually zero power and generates no noticeable heat.
