LORDWORLD 1.54 Inch E-Ink Display HAT 200x200 SPI Black White Red development board

SKU CH-7DAZ-BAYHB

A 1.54 inch e-paper HAT with a 200×200 resolution and SPI interface retains its image without power and runs on 3.3 V or 5 V logic

  • Content stays visible without power thanks to no backlight
  • Ultra-low power draw only during refresh cycles
  • 54 inch 200x200 SPI e-paper with red accent
  • Onboard voltage translator supports 3.3V and 5V MCUs
  • Example code provided for Raspberry Pi Jetson Nano STM32

1.54 Inch E-Ink HAT for Embedded Projects

This 1.54 inch e-paper HAT adds a 200x200 black white red display to Raspberry Pi boards, Jetson Nano or STM32 platforms. The SPI interface and onboard voltage translator allow direct connection to 3.3V or 5V microcontrollers without extra level shifting. Makers building low-power status panels, badge displays or sensor readouts can use the provided examples to start quickly.

SPI Interface Limits Refresh Rate and Wiring

The SPI bus drives the 1.54 inch screen, so full-panel updates take noticeable time and suit static or slowly changing content rather than animation. Only the SPI lines plus power and ground are required, keeping pin count low, but the host must tolerate the refresh latency. Continuous power is not needed to retain the last image, which suits battery-powered nodes that sleep between updates.

Simple Header Mount With Voltage Flexibility

The HAT aligns with the standard 40-pin header on supported Raspberry Pi models and matches similar pinouts on Jetson Nano or Nucleo boards. The onboard translator handles 3.3V and 5V logic automatically, so incorrect voltage selection rarely causes damage. Common issues include forgetting to enable SPI in the operating system config or mismatching the example code to the exact panel revision.

Perguntas sobre este artigo

Should I choose the black-white-red version or a different colour option?

This HAT is only offered in the black-white-red colour scheme, so there is no alternative palette to select.

What does the 200x200 resolution mean when the panel is driven by a Raspberry Pi?

The 200 by 200 pixel grid gives a 1.54 inch active area that updates in partial or full refresh modes, drawing power only during screen changes.

How fast is the SPI interface in practice and what does it limit?

The SPI bus drives the 200x200 panel at typical e-paper refresh rates, so full-screen updates take seconds rather than milliseconds.
