Integrated with the ESP32-D0WD, this 540*960 4.7″ E-ink display comes with 16MB Flash and 8MB PSRAM, which can work well with other touch screens. It supports 16 grayscale levels and partial refresh. Compared with a regular LCD, E-ink displays are easier on the eyes, which makes them a good choice for reading or viewing for longer periods. Meanwhile, E-ink screens are low power consumption and have the ability to retain the image even if power to the display is terminated.

A 6pin touch screen interface is reserved as an optional accessory to facilitate your application. There are 5 buttons on the side: 3 of them are custom buttons, which can define functions flexibly; and one of them is the reset button. It also reserves 7 expansion IO ports for connecting other devices. Its back is designed with a PH 2.0 pitch 3.7V battery connector.
