Overview

Drive 1.54–2.9" SPI e-ink panels from 3.3 or 5 V

The ET-D14 is built around the 24-pin 0.5mm FPC e-paper panels with SSD1680/SSD1681-class controllers (e.g. 1.54" 200×200, 2.13" 250×122, 2.9" 296×128) — panel bought separately. It talks over 4-wire SPI (write-only) + DC, RST, BUSY and runs from 3.3–5V; level-shifted inputs.

Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.

Good for

  • Battery dashboards that keep the image with no power
  • Shelf and room labels
  • Weather displays
