Waveshare 4.2″ E-Ink display module (400×300)

The Waveshare 4.2" E-Ink display module is a 400×300 resolution device with an embedded controller. The module communicates via an SPI interface and is compatible with controller boards like Raspberry Pi, Arduino, Nucleo, etc., thanks to its onboard voltage translator that supports both 3.3V and 5V MCUs. Notably, it doesn't require a backlight and can retain its last displayed content for an extended period, even after power down. Its ultra-low power consumption is another key feature, with power essentially only required for refreshing the display.
