LORDWORLD 1.54inch 200x200 Three-Color E-Ink Display Module (B)

SKU CH-4HSZ-M3ECE

A 1.54 inch E-Ink screen shows red, black and white at 200x200 resolution over SPI with an onboard 3.3V/5V level shifter and keeps its image without power

  • Three-colour E-Ink shows red, black and white
  • 200×200 resolution on a 1.54 inch screen
  • SPI interface connects to Raspberry Pi, Arduino or STM32
  • Onboard voltage translator handles 3.3 V and 5 V logic
  • Ultra-low power, only draws current during refresh

Compact E-Ink Module for Embedded Projects

The LORDWORLD 1.54inch display provides a 200x200 resolution screen with red, black and white three-colour output. It connects through an SPI interface and includes an onboard voltage translator for 3.3V or 5V logic compatibility. Development resources and manuals with examples for Raspberry Pi and STM32 platforms are supplied. This module suits makers adding persistent, low-power visual feedback to IoT edge devices.

Passive Display With Near-Zero Static Draw

No backlight is fitted so the panel retains the last image indefinitely without power. Energy is consumed only during a refresh cycle, making it suitable for battery-operated nodes that update infrequently. The embedded controller handles the driving waveforms, leaving the host MCU free for other tasks. Silent operation is inherent with no moving parts or fan requirement.

SPI Peripheral That Fits Tight Spaces

The board mounts directly to a controller via its SPI pins, needing no extra driver circuitry thanks to the integrated level shifter. Its small 1.54inch outline leaves room for sensors, radios or additional modules in a compact enclosure. Builders who need a larger viewing area, higher pixel density, or a parallel interface will have to select a different panel. The included example code accelerates integration with popular Raspberry Pi and STM32 development boards.

Otázky k tomuto produktu

How do I wire the SPI pins to a Raspberry Pi and which step is often missed?

Connect the module's SPI lines to the Pi's hardware SPI port and enable the SPI interface in raspi-config; the step many skip is enabling SPI before running the example code.

What part will need replacement first if I refresh the screen frequently?

The E-Ink panel itself wears out after many full refresh cycles, so the display module is the component that will eventually need replacing.

What limit appears first during continuous updating?

The full-refresh cycle time and the panel's rated refresh count are the first limits you hit when updating the 200x200 three-colour display repeatedly.
