A 2.13″ four-colour e-paper display HAT from Waveshare that plugs directly onto a Raspberry Pi via the standard 40-pin GPIO header. The panel renders red, yellow, black, and white ink for vivid, attention-grabbing content — perfect for price tags, shelf labels, and low-power status displays.
Unlike the raw display version, this HAT includes an onboard driver circuit with a voltage translator, making it compatible with both 3.3 V and 5 V microcontrollers. An additional SPI breakout header lets you connect it to Arduino, STM32, or Jetson Nano boards.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
-
A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GPIO
-
General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- IoT
-
Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- SPI
-
A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- STM32
-
STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
