5.83inch E-Paper Module 648x480 Black/White/Red/Yellow — SPI Shelf Label Display

High-resolution 648x480 e-paper suitable for a wide range of applications such as shelf labels and signage. Displays four colors: Black, White, Red and Yellow, with a clear, crisp image without requiring any backlight. The module includes an onboard controller and communicates via SPI, and it supports partial refreshing for faster updates. An onboard conversion chip makes the display compatible with 3.3V/5V single-chip microcomputer ports. Extremely low power usage — the panel only consumes power during refresh operations and holds the last image for an extended time when powered down.
