LORDWORLD 2.13inch E-Ink Display HAT 250x122 development board

SKU CH-RA4Y-QS6BJ

A 2.13 inch black-and-white e-paper HAT with 250 by 122 resolution, ultra-low power use and SPI pads for Raspberry Pi, Jetson Nano, Arduino or STM32 projects

  • Ultra-low power use, only draws current on refresh
  • 250x122 pixel resolution gives clear black-and-white text
  • Works with 3.3 V and 5 V boards via onboard translator
  • SPI pads let you connect Arduino, STM32 or other MCUs
  • Retains last image indefinitely without backlight or power

2.13inch E-Ink HAT for Raspberry Pi

This 2.13inch E-Ink Display HAT is a development board designed for Raspberry Pi Zero, 2B, 3B, 3B+ and 4B models. It also supports Jetson Nano platforms. The module provides a black and white e-paper screen with a 250x122 resolution for low-power visual output in maker projects.

Sustained load behaviour

The display consumes power only during refresh cycles and retains the last image indefinitely without any backlight. Ultra low power consumption makes it suitable for battery-operated devices that update intermittently. Partial refresh support allows faster updates for changing content sections.

SPI interface with 3.3V and 5V logic

Onboard voltage translation enables direct connection to 3.3V or 5V microcontrollers via the SPI interface. Preserved solder pads allow use with Arduino, Nucleo or STM32 boards. Buyers who need a parallel interface or higher colour depth should consider other display technologies.

Perguntas sobre este artigo

How much power does the 2.13inch E-Ink display draw when it runs continuously?

The module uses ultra-low power; it only consumes energy during a screen refresh and holds the last image indefinitely without power.

Which controller board and voltage level do I need to drive this HAT?

It fits Raspberry Pi Zero, 2B, 3B, 3B+, 4B and Jetson Nano directly, and the onboard translator lets you use 3.3V or 5V MCUs such as Arduino or STM32 via the SPI pads.

Will the SPI interface on this HAT work with my older Arduino Uno?

Yes, the preserved SPI solder pads and 3.3V/5V voltage translator make it compatible with legacy Arduino boards and other 5V microcontrollers.
