Small rectangular e-paper HAT board with 2.13 inch black and white display, 40 pin GPIO header, SPI interface, matte finish

Waveshare 2.13inch e-Paper Display HAT V4 250x122

SKU CH-W1RN-XGH9Y

A 2.13inch e-paper HAT with 250×122 resolution, SPI interface and ultra-low power consumption for Raspberry Pi and Jetson Nano

  • Retains image without power thanks to zero-backlight e-ink
  • Draws only 26.4mW while refreshing and
  • Fits Raspberry Pi 40-pin GPIO and Jetson Nano directly
  • Works with 3.3V or 5V MCUs via onboard voltage translator
  • Partial refresh in 0.3s and full refresh in 2s

2.13inch e-Paper HAT for Pi and Jetson

The Waveshare 2.13inch e-Paper Display HAT V4 is a 250×122 pixel black-and-white E-Ink module with a 40-pin GPIO header for Raspberry Pi series boards and Jetson Nano. It communicates over 3-wire or 4-wire SPI and includes an onboard voltage translator for 3.3V and 5V logic. No backlight is fitted; the panel retains its last image without power.

Makers needing persistent low-power readouts

This HAT suits builders adding shelf labels, sensor dashboards or badge displays that must stay visible for weeks on a coin cell. The 0.3 s partial refresh and 26.4 mW typical refresh power support frequent updates. Buyers who want greyscale, colour or resolutions above 250×122 should look at larger e-Paper modules. Projects requiring video-rate animation or backlit viewing are not a fit.

Drops onto a 40-pin header, frees the rest

The board measures 65×30.2 mm with a 48.55×23.71 mm active area and 0.194 mm dot pitch. It draws <0.01 µA in standby, leaving the Pi’s remaining GPIO pins and USB ports free for sensors, networking or storage. Example code for Raspberry Pi, Jetson Nano, Arduino and STM32 is provided online, so integration starts without writing a driver from scratch.

이 상품에 대한 질문

Which Raspberry Pi boards provide the 40-pin GPIO header this HAT needs?

The HAT fits the standard 40-pin GPIO header found on Raspberry Pi 5, 4B, 3B+, 3B, 2B, A+, Zero W, WH and Zero 2 W boards.

Can the display share the SPI bus with other 3.3 V or 5 V devices I already use?

Yes, the onboard voltage translator makes the SPI interface compatible with both 3.3 V and 5 V microcontrollers, so it can sit on a shared bus with Arduino or STM32 modules.

How do I confirm the panel is refreshing correctly after wiring it up?

Run the supplied example code; a full refresh takes 2 s and a partial refresh 0.3 s, and the screen should hold the last image with no power applied.
