10.85 inches EPaper HAT+ Display Module A lowpower, paperlike display module designed for embedded projects and single board computers. The passively reflective epaper panel shows red, yellow, black, and white content with long image retention and minimal power use, making it ideal for batterypowered and alwayson applications. Key benefits Extremely low power consumption: power is required only to refresh the screen; the display retains the last image without power. Paperlike readability: passively reflective panel is easy to read in ambient light and works well for static or infrequently updated content. Broad compatibility: SPI interface and onboard voltage translation support connection to common controllers and microcontrollers. Faster integration: follows the HAT+ standard for improved interoperability and fits a standard 40pin GPIO extension header on Raspb Pi series boards, simplifying addon development. Features Screen size: 10.85 inches, resolution 1360 x 480 Viewing angle greater than 170 degrees for wide visibility Display colors: red, yellow, black, white Greyscale: 2 levels Communication: SPI interface for reliable, lowpin communication Display type: passively reflective epaper; ambient light required for viewing No backlight; image remains visible after power off until the next refresh Onboard voltage translator compatible with 3.3V and 5V microcontrollers Adopts Raspb Pi HAT+ standard and uses a standard Raspb Pi 40pin GPIO extension header Development resources provided online, including EPaper Driver HAT circuit diagram and examples for Raspb Pi and STM32 Compatibility Designed for easy connection to controllers such as Raspb Pi series, ESP32, STM32, and other SPIcapable MCUs Onboard translator allows direct use with either 3.3V or 5V logic Package contents 10.85 inch ePaper HAT+ (G) x1 MX1.25 10pin cable x1 Screws pack x1 Practical use scenarios Electronic shelf labels and tags where low power and long image retention reduce maintenance and battery changes Information displays such as timetable boards, meeting room signs, or status panels that update occasionally but must stay readable between updates Batterypowered IoT dashboards or sensor readouts that require clear, contrast text and graphics with minimal energy use Technical note The display is reflective and requires ambient light for viewing. Refresh operations consume power; no power is needed to hold the displayed image between refreshes. Development materials and example code are available to help integrate the HAT with supported controllers.
