ESP32 4.7”E-ink Display 960×540 Wiki - DFRobot

Introduction

This is an E Ink display controller device designed to be used with a touchscreen. It features the ESP32-S3-WROOM-1-N16R18 controller with 16MB Flash and 8MB PSRAM built-in. The front side includes a 4.7-inch E Ink display with a resolution of 540x960, supporting 16-level grayscale and partial refresh.

In comparison to a regular LCD screen, an E Ink display provides users with a better text reading experience, along with low power consumption and image retention when powered off. It also includes a 6-pin touchscreen interface for optional accessories, catering to your specific application needs. On the side, there are 3 reserved buttons, with 2 customizable buttons for flexible functionality and one reset button. Additionally, it features a 40-pin header compatible with Raspberry Pi's BUS interface. On the back, there is a PH 2.0 spaced 3.7V battery socket.
