WaveShare 2.13inch E-Ink Display HAT V3 Black/White 250x122 SPI

SKU CH-43HE-N7JTQ

2.13-inch SPI e-paper HAT shows black and white at 250×122, keeps the image without power and refreshes partially in 0.3 s

  • CPU TypeOther
  • Ultra-low power draw extends battery life
  • 250 × 122 pixel black/white resolution
  • 3 s partial refresh updates content quickly
  • 40-pin GPIO header fits Raspberry Pi boards
  • Retains image without power for shelf labels

Compact E-Ink HAT for Pi and Jetson

This 2.13inch e-paper HAT adds a 250 by 122 pixel black-and-white display to Raspberry Pi boards and Jetson Nano through the 40-pin GPIO header. The embedded controller communicates over SPI, making it suitable for low-power readouts such as shelf labels or industrial instruments. No backlight means the last image remains visible without power.

Partial refresh and preserved SPI pads

Partial refresh completes in 0.3 seconds and draws about 26.4 milliwatts, so frequent updates keep consumption low. Preserved solder pads expose the SPI lines for direct connection to Arduino, Nucleo or other 3.3 volt and 5 volt microcontrollers. An onboard voltage translator handles both logic levels automatically.

65 by 30.2 millimetre board with wide viewing angle

The outline measures 65 by 30.2 millimetres with an active area of 48.55 by 23.71 millimetres and a 0.194 millimetre dot pitch. The panel offers a 170 degree viewing angle and retains its image indefinitely when unpowered. Builders needing colour, greyscale or larger resolutions should look elsewhere.

Questions about this item

Will the e-ink panel itself need replacing after many refresh cycles?

The panel has no backlight and retains its last image without power, so there is no light source to degrade; the display is rated for repeated partial and full refreshes without a specified cycle limit.

What limits continuous operation — the SPI bus speed or the panel refresh time?

A full refresh takes 2 seconds and a partial refresh 0.3 seconds, so the panel's own refresh cycle is the bottleneck for sustained updates.

How much heat or power does the HAT add when it updates every few minutes all day?

Each refresh draws about 26.4 mW and the board idles at micro-watt levels, so running all day adds negligible heat and minimal load on a 3.3 V or 5 V supply.
