Description Waveshare Pico-ePaper-2.66 is a 2.66inch black and white e-paper display module designed for Raspberry Pi Pico. It combines a 296 × 152 resolution panel with a Pico-compatible header layout, making it a practical choice for low-power labels, compact status screens, handheld readouts, and Pico-based display projects. E-paper keeps the last image visible even after power is removed, so it is especially useful when you need ultra-low power consumption, a paper-like viewing experience, and a display that remains readable under ambient light without a backlight. Features Designed for Raspberry Pi Pico with onboard header alignment for direct integration. 296 × 152 resolution on a 2.66inch e-paper panel for crisp text and simple graphics. Black and white display with a wide viewing angle above 170°. No backlight, so the display remains comfortable to read under ambient lighting. Ultra-low power design, with power mainly consumed during refresh. Partial refresh support for quicker updates in dynamic Pico applications. SPI interface keeps wiring simple and reduces required GPIO usage. Development resources included for Pico C/C++ and MicroPython projects. Specifications Operating voltage 3.3V Display color Black, white Interface 3-wire SPI, 4-wire SPI Grey scale 2 Outline dimensions 74.00 × 37.50mm Partial refresh time 0.3s Display size 60.088 × 30.704mm Full refresh time 5s Dot pitch 0.203 × 0.202mm Refresh power 42.4mW (typ.) Resolution 296 × 152 pixels Standby current 170° Compatible controller Raspberry Pi Pico Applications This Pico e-paper display is well suited for electronic shelf labels, price tags, asset tags, battery-powered data displays, industrial readouts, smart desk signs, and Pico low-power UI projects. It is also a good fit for projects that need a display which remains visible after shutdown. Product List Item Quantity Pico-ePaper-2.66 1 Standoffs pack 1 Other Content Pinout and interface reference are especially important on this model because the board exposes the Pico-side control signals clearly for quick prototyping. The onboard interface design keeps the module easy to integrate into MicroPython and Pico SDK projects. Resources Waveshare Pico-ePaper-2.66 Wiki Waveshare e-Paper Common Questions Raspberry Pi Pico Official Documentation Raspberry Pi Pico Python SDK Raspberry Pi Pico C/C++ SDK FAQ Does this Pico e-paper display need constant power to keep the image visible?No. Like other e-paper modules, it can keep the last displayed content visible even after power is removed. Is this display suitable for fast animation?No. This module is optimized for low-power static or lightly changing content, not for video-like animation. Why does the screen flash during refresh?The flashing effect during a global refresh is a normal behavior of e-paper technology. What projects is this module best suited for?It works especially well for Raspberry Pi Pico status panels, shelf labels, compact dashboards, industrial instruments, and battery-powered information displays.
