The display supports 16 grayscale levels and partial refresh for faster screen updates.\n\nThe 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.\n\nKey Features\n\n\nIntegrated ESP32 – ESP32-WROVER-E with 16MB Flash and 8MB PSRAM\n\n4.7\" E-Ink Display – 540 × 960 resolution with 16 grayscale levels\n\nPartial Refresh – Faster updates without full screen redraw\n\nBattery Ready – PH 2.0 connector with charge/discharge protection\n\nExpandable – 7 expansion I/O ports and 6-pin touch interface\n\n3 Custom Buttons – User-definable for flexible interaction\n\n\nSpecifications\n\n\nController – ESP32-WROVER-E (ESP32-D0WDQ6 V3)\n\nFlash – 16MB\n\nPSRAM – 8MB\n\nDisplay Size – 4.7 inches\n\nResolution – 540 × 960 pixels\n\nGrayscale Levels – 16\n\nCustom Buttons – 3\n\nExpansion I/O – 7 ports\n\nBattery Connector – PH 2.0 (3.7V)\n\nBattery Protection – HX6610S charge/discharge IC\n\nTouch Interface – 6-pin (touchscreen sold separately)\n\n\nIdeal For\n\nDesktop weather stations\nSmart shelf labels and signage\nIoT information displays\nMessage boards\nSTEM education projects\n\n\nPackage Contents\n\n1× 4.7\" ESP32 e-ink screen\n1× USB to Type-C data cable (30cm)\n1× Power cable\n\n\nResources\n\nDFRobot Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2703,"title":"Default Title","sku":"DF-DFR0835","price":101.14,"on_sale":false,"in_stock":true,"available_quantity":4,"option1":"Default Title"}]}
