4.2-Inch E-Ink Display Module

Overview

The 4.2-inch E-Ink display module features a resolution of 400×300 pixels and is equipped with an embedded controller that communicates through an SPI interface. This display is particularly advantageous due to its ultra-low power consumption, wide viewing angles, and the ability to maintain content visibility without power, making it ideal for applications such as shelf labels and industrial instruments.

Key Features

• Persistent Display: Retains the last displayed content indefinitely even when powered off.
• Energy Efficient: Consumes minimal power; energy is primarily needed only during refresh cycles.
