LORDWORLD 2.9inch E-Paper Display Module 296×128 Black/White development board

SKU CH-MV0D-JDR2T

2.9 inch e-paper display shows 296×128 black and white pixels via SPI with ultra-low power use

  • Retains image without power thanks to no-backlight design
  • Ultra-low power draw only during refresh cycles
  • SPI interface minimises GPIO pin usage
  • 296×128 pixel resolution on 2.9 inch panel
  • Black-and-white e-paper suited for IoT edge devices

Target platform and role

This e-paper display module is built for Raspberry Pi Pico projects that need a persistent, readable screen. The 2.9inch panel shows 296×128 pixels in black and white without a backlight. It draws power only while refreshing, so battery-powered sensors or data loggers can run for long periods. Developers working on low-power IoT edge devices will find the SPI interface easy to integrate with minimal GPIO usage.

Upgrade path and trade-offs

It replaces basic character LCDs or OLED modules when you need the image to stay visible after power is removed. The jump is worth it for projects that update infrequently and must survive power loss without losing the display. It is not suited for animations, video or frequent full-screen redraws because the refresh cycle is slow and only partial refresh is supported. Buyers who need colour, greyscale or faster update rates should look elsewhere.

Capacity and headroom

The 296×128 resolution comfortably fits sensor readouts, status icons, QR codes or several lines of text. The SPI bus keeps pin count low, leaving most Pico GPIOs free for other peripherals. Power consumption stays near zero between updates, giving excellent headroom for coin-cell or solar-powered builds. The module runs out of steam when the application demands rapid screen changes, full-motion graphics or colour information.

Questions sur cet article

How many IO pins does the 2.9 inch SPI display need?

The SPI interface requires minimal IO pins for connection to a Raspberry Pi Pico.

What wiring step is often missed when connecting this e-paper module?

Ensure the SPI pins are matched correctly to the Pico's hardware SPI port and that the module shares a common ground with the board.

Does the 296×128 panel need periodic refreshing to retain its image?

No backlight is used and the last content stays visible for a long time even when power is removed.
