- Retains image without power thanks to zero backlight
- Draws power only during refresh for ultra-low consumption
- Fits Raspberry Pi boards via standard 40-pin GPIO header
- Connects to host boards through USB, SPI, I80 or I2C
- Sharp 7.8 inch 1872×1404 resolution driven by IT8951 controller
7.8-inch E-Ink HAT for Raspberry Pi
This development board adds a 7.8-inch black-and-white e-paper screen to Raspberry Pi boards through the standard 40-pin GPIO header. It suits makers and engineers building low-power IoT edge devices that need persistent, readable output without a backlight.
Passive operation with refresh-only power draw
The display retains the last image indefinitely after power is removed because it has no backlight. Power is consumed only during a screen refresh, so normal use adds negligible thermal load and produces no fan noise.
IT8951 controller with four host interfaces
The onboard IT8951 controller exposes USB, SPI, I80 and I2C paths, letting the same HAT connect to Raspberry Pi, Nucleo or other host boards. Partial refresh support lets software update only changed regions, further reducing refresh time and energy use.

Jautājumi par šo preci
How do I attach the 7.8inch E-Ink HAT to a Raspberry Pi using the 40PIN GPIO extension header?
Align the HAT's 40PIN GPIO extension header with the Raspberry Pi's 40-pin header and press down firmly to seat all pins; the common mistake is not fully seating the connector, leaving intermittent contact.
What maintenance does the 7.8inch E-Ink display require over time?
The display has no backlight and retains the last image without power; maintenance is limited to keeping the screen surface clean and ensuring the USB, SPI, I80 or I2C connections remain secure.
What is the first limitation when using partial refresh repeatedly on the 1872×1404 panel?
Repeated partial refreshes can cause ghosting artifacts to accumulate on the 1872×1404 panel, requiring a full refresh to clear the residual image.
