LORDWORLD

LORDWORLD Four Color 2.13inch E-Ink Display HAT (G) 250x122 development board

SKU CH-8SBC-A7WM9

A 2.13 inch four-colour e-paper HAT with 250x122 resolution, SPI control and 3.3 V or 5 V logic for Raspberry Pi, Jetson Nano, Arduino or STM32 projects

  • Four-colour e-paper shows red, yellow, black and white
  • 250 by 122 pixel resolution on a 2.13 inch screen
  • SPI interface connects to Raspberry Pi, Jetson Nano, Arduino, STM32
  • Onboard voltage translator handles 3.3 V and 5 V logic levels
  • Zero power to hold image, only draws current during refresh

What this HAT adds to your board

The LORDWORLD Four Color 2.13inch E-Ink Display HAT (G) is a compact development board that mounts directly on a Raspberry Pi, Jetson Nano, Arduino or STM32 platform. It provides a 2.13 inch electronic paper screen with a 250x122 pixel grid. The module draws power only while refreshing the image and retains the last picture indefinitely without a backlight.

Resolution and colour set the limits

The panel shows 250 by 122 pixels in four colours: red, yellow, black and white. No other palette or higher density is available on this part, so graphics and text must fit within that grid. The SPI interface and onboard voltage translator handle both 3.3 V and 5 V logic, but the resolution and colour count are fixed by the display itself.

Suits low-power status panels.

Makers building shelf labels, sensor readouts or badge displays that update infrequently will benefit from the ultra-low draw and persistent image. Projects needing animation, greyscale depth, full-colour photographs or a larger viewing area should look at a different display technology.

Întrebări despre acest articol

How does the 250x122 resolution look on the 2.13 inch screen?

The 2.13 inch panel shows 250 by 122 pixels in red, yellow, black and white, giving a compact four-colour image that stays visible without power.

What does the SPI interface limit in practice?

SPI sets the refresh speed; the display only draws power during updates, so the bus bandwidth caps how fast you can change the four-colour image.

What do I need to mount this HAT on a Raspberry Pi?

The board plugs directly onto the Raspberry Pi GPIO header; the onboard voltage translator makes it compatible with 3.3 V and 5 V logic.
