Waveshare 2.13-inch E-Ink HAT V4 (250×122)

Description

The Waveshare 2.13-inch E-Ink HAT V4 is a 250×122 black-and-white e-paper display with an embedded controller, SPI communication and partial-refresh support. Its standard 40-pin Raspberry Pi HAT connection makes it the display used by the tested Pi Meowagotchi setup.

Why it fits Pi Meowagotchi

• The retailer identifies these units as V4, matching the project default driver epd2in13_V4.
• The 250×122 resolution matches the panel used during Pi Meowagotchi development and testing.
• Partial refresh supports the project’s animated cat without a full-screen flash on every frame.
• The HAT mounts directly on a Raspberry Pi with a populated standard 40-pin GPIO header.

Before buying

• This listing includes the e-paper HAT, not a Raspberry Pi, storage or power supply.
• Confirm the retailer still supplies the V4 revision before ordering; Waveshare panel revisions require different driver modules.
• Enable SPI on the Raspberry Pi before installing Pi Meowagotchi.
• E-paper panels have a finite refresh life. The project lets you adjust animation and refresh cadence.
• Price, availability and package contents can change. Check the retailer listing before ordering.
