LORDWORLD 2.7inch E-Ink Display HAT 264x176 development board

2.7 inch E-Ink HAT for Raspberry Pi

This 2.7 inch e-paper HAT provides a 264 by 176 pixel black and white display for Raspberry Pi boards and Jetson Nano. It mounts on the standard 40 pin GPIO header and needs no backlight, so the last image remains visible after power is removed. Makers building low power status panels or shelf labels will find it a good fit. Buyers who want colour output or a larger viewing area should look elsewhere.

SPI interface and voltage limits

Communication uses a SPI bus, which keeps wiring simple but limits refresh speed compared to parallel interfaces. The onboard voltage translator accepts 3.3 V and 5 V logic levels, letting the module connect directly to Arduino, STM32 or Nucleo boards without extra level shifters. No other interface or protocol is supported. Projects that need rapid animation or video playback will find the SPI bandwidth insufficient.

Mounting and common issues

The HAT plugs straight onto the 40 pin header, so no soldering is required for Raspberry Pi or Jetson Nano. Example code for Raspberry Pi, Jetson Nano, Arduino and STM32 is supplied in the development resources. A frequent problem is forgetting to enable the SPI kernel module on the Pi before running the demos. Another is wiring the module to a 5 V only controller without confirming the translator is active, which can cause blank screens.
