MCDODO 2.13inch E-Ink Display HAT V4 250x122 SPI

Compact E-Ink HAT for Raspberry Pi Projects

This 2.13inch E-Ink Display HAT V4 adds a 250x122 pixel screen to Raspberry Pi boards from the Pi 5 down to the Zero family and Pico variants. It connects through the standard 40PIN GPIO header and communicates via SPI. Makers building shelf labels, instrument readouts or portable status panels can use the onboard voltage translator that works with both 3.3V and 5V logic. The board also supports Jetson Nano and Arduino-class controllers for wider prototyping.

40-pin header and SPI make integration

The HAT sits directly on the Raspberry Pi GPIO header without extra cabling, while the SPI interface keeps wiring simple for other microcontrollers. A built-in level shifter handles 3.3V and 5V systems so the same module moves between platforms. Partial refresh support lets developers update only changed screen areas, reducing full redraw cycles. Online manuals cover Raspberry Pi, Jetson Nano, Arduino and STM32 examples to accelerate first boot.

Ultra-low power with persistent image retention

The electrophoretic panel draws power only during refresh events and holds the last image indefinitely without electricity. No backlight means zero standby current, ideal for battery-powered or energy-harvesting nodes. Wide viewing angles keep data readable from off-axis positions in industrial or retail settings. The V4 screen revision maintains full compatibility with earlier V3 code while adding a fast-refresh demo for smoother animations.
