WaveShare DEBO EPA 4.2 - Developer Boards - Display ePaper 4.2"" black/white

This is a 4.2-inch E-Ink / E-Paper display module with a resolution of 400 x 300 pixels, featuring an integrated controller that communicates via the SPI interface. With its extremely low power consumption, it is ideal for battery-operated applications. These displays are also used as price tags, which can operate for several years on a single battery. The display offers a very good viewing angle and can be easily read even in sunlight. Included in the package is a connection cable that allows you to easily connect the display to a Raspberry Pi. For an Arduino Uno or if you want to plug it onto a breadboard, you will need 8 male/male Dupont cables.

Features:

• Displays retain their content even without power supply.
• Onboard level shifter, making it compatible with 3.3 V and 5 V microcontrollers.
• Ultra-low power consumption. Power is primarily needed only for refreshing.
• SPI interface for connection to controller boards like Raspberry Pi, Arduino, ESP8266, or ESP32.
• Good documentation and example code are available.
• Programming examples for the following controllers are available: Arduino, STM32, and Raspberry Pi.
