LORDWORLD 2.9inch E-Paper Display 296x128 SPI Development Board

SKU CH-N403-0XH49

A 2.9 inch e-paper display with 296x128 resolution, SPI interface, and 3.3V/5V compatibility for microcontroller projects

  • Retains image without power thanks to backlight-free e-paper
  • Ultra-low consumption — draws current only during refresh
  • SPI interface connects to Raspberry Pi, Arduino, Nucleo boards
  • On-board voltage translator supports 3.3 V and 5 V MCUs
  • Includes examples for Raspberry Pi, Jetson Nano, Arduino, STM32

Target hardware

The LORDWORLD 2.9inch E-Paper Display is a compact development board designed for makers and engineers building low-power IoT edge devices. Its 296x128 resolution suits status readouts, sensor dashboards or badge-style projects where a persistent image is needed without constant refresh.

Build integration

The module communicates over SPI and includes an onboard voltage translator, allowing direct connection to 3.3V or 5V microcontrollers such as Raspberry Pi boards, Arduino compatibles or STM32 Nucleo kits. Example code and documentation are supplied for each supported platform, reducing bring-up time for the display subsystem.

Sustained behaviour

With no backlight, the panel retains the last frame indefinitely after power is removed, drawing energy only during the brief refresh cycle. This ultra-low consumption profile makes the board practical for battery-operated or energy-harvesting nodes that update infrequently over long deployments.

أسئلة حول هذا المنتج

How many SPI pins does the 2.9inch E-Paper Display need on my Raspberry Pi?

The module uses a standard 4-wire SPI bus plus a few control lines, so it fits on the regular GPIO header of any Pi model listed.

Will the 2.9 inch screen heat up or make noise if I leave it showing the same image for days?

E-ink only draws power while refreshing, so once the 296x128 image is stable the board stays cool and completely silent.

Which controller boards can drive the 2.9inch E-Ink Display Module without extra level-shifting?

The onboard voltage translator makes it directly compatible with 3.3V and 5V MCUs such as Raspberry Pi, Arduino, STM32 and Jetson Nano.
