640x384, 7.5inch E-Ink display HAT for Raspberry Pi (WS-13504)

Overview

This is an E-Ink display HAT for Raspberry Pi, 7.5inch, 640x384 resolution, with embedded controller, communicating via SPI interface.

Due to the advantages like ultra low power consumption, wide viewing angle, great effect under sunlight, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.

Features

• No backlight, keeps displaying last content for a long time even when power down
• Ultra low power consumption, basically power is only required for refreshing
• Compatible with Raspberry Pi 2B/3B/Zero/Zero W
• SPI interface, for connecting with other controller boards like Raspberry/Arduino/Nucleo, etc.
• Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
