2.66-inch E-Paper Module for Pico

This 2.66-inch e-paper display module targets makers building low-power projects with a Raspberry Pi Pico. It shows black and white content at 296×152 pixels and retains the last image without any backlight when power is removed. The board connects through a standard SPI interface that uses only a few GPIO pins. Example code in C/C++ and MicroPython is included to speed up development.

Thermals noise and power draw

Because the panel is bi-stable, it draws current only during a refresh and consumes virtually nothing while holding a static image. No backlight means no continuous illumination load and no fan or active cooling is required. The board therefore runs silently and stays cool even during frequent partial updates. This behaviour suits battery-powered or solar-charged nodes that must operate for weeks between charges.

Build quality and connectors

The compact PCB exposes the SPI pins and power rails on a standard header that plugs directly into a Pico or a compatible breadboard layout. Mounting holes are not described in the data, so mechanical fixing relies on the pin friction or an external carrier. The supplied documentation covers wiring, driver initialisation and partial-refresh timing for both supported languages. Projects needing colour, greyscale or a larger active area will require a different module.

Domande su questo articolo

How do I wire the 2.66inch SPI e-paper to a Raspberry Pi Pico and what pin-mapping mistake should I avoid?

Connect the module's SPI pins to the matching Pico GPIO header using the provided wiring diagram; the common error is swapping the CS and DC lines, which prevents the display from initialising.

What part of the 296×152 display will need attention after many refresh cycles?

The e-paper film itself retains images without power, so no scheduled replacement is required; only the connector or flex cable may wear if repeatedly disconnected.

At what point does the 2.66inch panel's refresh speed become the bottleneck during sustained updates?

Partial refresh is supported, but full-screen updates take several hundred milliseconds, so the refresh interval is the first limit hit in rapid-redraw applications.
