Boardoza E-Paper Driver 24 Pin Breakout Board
The Boardoza E-Paper Driver 24-Pin Breakout Board makes it easy to add a clear, paper-like display to microcontroller-based projects. E-paper displays are highly readable in bright environments and can retain the last displayed image even after power is removed. Because they primarily consume power only during screen updates, they are well suited for battery-powered applications such as electronic shelf labels, smart badges, price tags, information panels, industrial indicators, and low-power IoT devices. The board features a standard 24-pin FFC/FPC connector and the power circuitry required to operate compatible e-paper panels, eliminating the need for a separate driver circuit. It supports SPI- and I²C-compatible signals, provides a busy-status output to indicate when the display is refreshing, and can be used with compatible monochrome and multi-color e-paper panels, including black-white-red and black-white-red-yellow display types.
