LORDWORLD

LORDWORLD 3.52inch E-Paper Development Board

SKU CH-FB28-17HKA

A 3.52inch e-paper development board with a 40-pin GPIO header for Raspberry Pi and Jetson Nano, ultra-low power use and 3.3V/5V logic compatibility

  • Raspberry Pi 40-pin header for direct board stacking
  • No backlight retains image indefinitely after power loss
  • Ultra-low power draws energy only during screen refresh
  • 3 V and 5 V logic support via onboard translator
  • 52 inch e-paper display for clear, readable output

Target platforms

The LORDWORLD 3.52inch E-Paper Development Board adds a 3.52inch electronic-paper display to Raspberry Pi series boards and Jetson Nano via the standard 40PIN GPIO extension header. It is aimed at makers and IoT developers who need a persistent, low-power visual output for edge devices.

Sustained behaviour

The panel requires power only during refresh cycles and retains the last image indefinitely without a backlight when power is removed. Ultra low power consumption makes it suitable for battery-operated or energy-harvesting projects that update the display infrequently.

Voltage compatibility

An onboard voltage translator allows direct connection to both 3.3V and 5V microcontrollers, removing the need for external level-shifting circuitry. The 40PIN header matches the Raspberry Pi GPIO layout, so the board plugs in without adapters or custom wiring.

Questions about this item

How much power does the 3.52inch e-paper draw when it refreshes all day?

It consumes ultra-low power and only requires energy during screen refreshes; the display holds the last image without any backlight when power is removed.

Which host boards can I plug the 40PIN GPIO header into?

The onboard 40PIN extension header fits Raspberry Pi series boards and Jetson Nano, and the voltage translator makes it compatible with 3.3 V or 5 V microcontrollers.

Will the display work alongside older 5 V microcontrollers I already own?

Yes, the built-in voltage translator allows direct connection to 5 V MCUs as well as 3.3 V logic without extra level-shifting hardware.
