LORDWORLD 1.54 Inch Tri-Color E-Ink Display Module 200x200 3.3V

SKU CH-80RT-FZR5K

A 1.54 inch e-paper panel shows red, black and white at 200 by 200 resolution, retains its image without power and draws energy only during refresh over a 3.3 V SPI link

  • Displays three colours for clear status indicators
  • 200 x 200 pixel resolution gives sharp text and graphics
  • Retains image without power so battery lasts longer
  • SPI interface connects directly to Raspberry Pi and STM32 boards
  • Onboard voltage translator allows safe use with 3.3 V and 5 V MCUs

Compact E-Ink for IoT prototypes

This 1.54 inch tri-colour E-Ink module shows red, black and white at 200 by 200 resolution. It targets makers building low-power IoT edge devices that need a persistent display without constant refresh cycles. The embedded controller handles driving logic over a standard SPI link. No backlight means the last image remains visible after power is removed.

Embedded controller and voltage translator

The onboard controller removes the need for external waveform generation, simplifying firmware on Raspberry Pi, STM32, Nucleo or Jetson Nano boards. An integrated voltage translator allows direct connection to both 3.3 V and 5 V microcontrollers without level-shifting hardware. Ultra-low power draw means energy is only consumed during screen updates, extending battery life in remote sensors.

SPI wiring and refresh timing

Connection uses a standard four-wire SPI bus plus control lines, so pin count stays modest for small MCUs. The main integration task is matching the display’s refresh sequence and timing constraints in software libraries. Partial updates are not supported on this panel, so full-screen redraws cause a visible flash each time. Ensure your MCU can supply the required 3.3 V logic levels.

Perguntas sobre este artigo

Will the 1.54 inch E-Ink panel need a backlight replacement over time?

No backlight is fitted; the display keeps the last image without power, so there is no backlight to wear out or replace.

What limits continuous operation of the 200x200 three-colour E-Ink module?

The embedded controller only draws power during refresh cycles, so the practical limit is the refresh rate rather than sustained power or heat.

How much heat or noise does the 3.3 V SPI E-Ink display produce when running all day?

It generates virtually no heat and no audible noise because power is only needed for brief refreshes and the panel has no backlight or moving parts.
