This 4.7" e-ink display board integrates an ESP32-WROVER-E module (ESP32-D0WDQ6 V3) with 16MB Flash and 8MB PSRAM, providing a complete development platform for low-power e-ink projects. The display supports 16 grayscale levels and partial refresh for faster screen updates.

The board features 3 custom buttons, a reset button, 7 expansion I/O ports, a 6-pin touch screen interface (for an optional capacitive touchscreen panel), and a PH 2.0 battery connector with built-in charge/discharge protection (HX6610S). E-ink displays retain their image even when power is disconnected, making this ideal for battery-powered information displays.
