Small rectangular 2.9 inch e-paper HAT with red black white display for Raspberry Pi Pico

LORDWORLD

LORDWORLD 2.9inch E-Paper Display Module (B) HAT 296×128 for Raspberry Pi Pico

SKU CH-NP95-95M7M

A 2.9 inch e-paper HAT for Raspberry Pi Pico shows 296×128 pixels in red, black and white without backlight, retains images after power loss and draws power only during refresh over SPI

  • Retains image without power thanks to zero-backlight e-paper
  • Ultra-low consumption draws energy only during screen refresh
  • SPI connection uses minimal GPIO pins on Pico
  • Three-colour 296×128 panel shows red, black and white
  • Compact 2.9 inch HAT plugs directly onto Raspberry Pi Pico

What it is

The LORDWORLD 2.9inch E-Paper Display Module (B) HAT provides a 296×128 pixel red, black and white screen that plugs directly onto a Raspberry Pi Pico. It uses an SPI interface that needs only a few IO pins, leaving the rest free for sensors or other peripherals. With no backlight, the last image stays visible for a long time after power is removed, making it suitable for low-duty-cycle readouts.

Compatibility check

Verify that your Pico has the SPI pins exposed and that your project can allocate the required IO lines for the display. The module draws power only during refresh cycles, so confirm your power budget can supply the brief current spikes when updating the screen. No backlight driver or extra voltage rails are needed, simplifying the wiring.

Thermals and power

Because the panel consumes power only while refreshing, heat output is negligible during static display periods. There are no active cooling components, so the board runs silently in normal use. Overall energy draw remains very low, allowing extended operation from small batteries or USB power without thermal concerns.

Întrebări despre acest articol

Does the module ship with a Raspberry Pi Pico included or must I buy the board separately?

The HAT plugs directly onto a Raspberry Pi Pico; the Pico itself is not included and must be purchased separately.

Which resolution variant should I choose for this display?

This module has a single 296×128 pixel resolution; no other resolution option is offered for this model.

How long does the 296×128 red/black/white image remain visible after power is removed?

With no backlight the last refreshed content stays visible indefinitely until the next SPI update.
