Small rectangular e-ink display HAT with black and white screen for Raspberry Pi Pico

LORDWORLD

LORDWORLD 2.9inch E-Ink Display HAT 296×128 Pixels Black White Two Color E-Paper Module for Raspberry Pi Pico

SKU CH-XMRJ-ABNT6

A 2.9 inch e-paper module with 296×128 resolution that retains images without power and connects via SPI to a Raspberry Pi Pico

  • Retains image without power thanks to no backlight
  • Ultra-low consumption only draws current during refresh
  • 296×128 pixel two-colour e-paper gives crisp text
  • SPI interface needs minimal GPIO pins on Pico
  • C/C++ and MicroPython examples speed up development

Compact E-Ink HAT for Pico projects

The LORDWORLD 2.9inch E-Ink Display HAT adds a 296×128 pixel black-and-white screen to a Raspberry Pi Pico board. It connects through an SPI interface that uses only a few GPIO pins, leaving the rest free for sensors or actuators. Example code in C/C++ and MicroPython is included so developers can start drawing text or graphics immediately.

Passive display with near-zero idle draw

No backlight is fitted, so the panel retains its last image indefinitely after power is removed. Power is consumed only during a refresh cycle, making the module suitable for battery-powered devices that update infrequently. The SPI link keeps wiring simple and does not add audible noise or measurable heat to the host board.

Upgrade from LED or LCD modules needing constant

Makers replacing always-on character LCDs or seven-segment LED displays gain weeks of runtime on the same cell because the e-paper draws nothing while static. The jump is worthwhile when the application shows slowly changing data such as sensor logs, price tags or status badges and can tolerate the refresh latency of electrophoretic technology.

Questions about this item

How do I attach the 2.9inch E-Ink Display HAT to a Raspberry Pi Pico?

Align the HAT's header pins with the Pico's GPIO pins and press firmly until fully seated; the SPI interface uses minimal IO pins, so double-check the pinout in the manual to avoid offsetting the connector by one row.

Will the 296×128 pixel panel need any periodic maintenance or component replacement?

The e-paper module has no backlight and retains its last image without power; it requires no scheduled maintenance or consumable replacements, only occasional cleaning of the display surface if dust accumulates.

What is the first limitation I will hit when refreshing the display continuously?

Partial refresh is supported, but each full-screen update on the 2.9inch panel takes noticeable time, so sustained animation or rapid data changes will be limited by the e-paper's inherent refresh cycle speed.
