Waveshare 13.3 inch 3 Color E-Ink Display 960x680 E-Paper is a 13.3 inch tri-color e-paper HAT (B) designed for Raspberry Pi, Jetson Nano, RDK X3, Arduino, STM32, and other SPI-compatible controller platforms. It provides a 960 x 680 red / black / white reflective display with partial refresh support, making it a strong option for large-format electronic signage and low-power display projects that need limited accent color. This model uses 3-wire SPI / 4-wire SPI, includes an onboard voltage translator compatible with 3.3V and 5V MCUs, and is especially suitable for price tags, shelf labels, asset tags, conference name tags, warning labels, information boards, and industrial displays where red highlighting improves readability. It is the right choice when a standard black-and-white e-paper is too plain, but you still want the simplicity and low power behavior of a SPI e-paper module. Features 13.3 inch red / black / white e-paper display with 960 x 680 resolution. Partial refresh support with faster local update behavior than full refresh. 3-wire SPI and 4-wire SPI communication. Standard Raspberry Pi 40PIN GPIO extension header for Raspberry Pi series boards and Jetson Nano. Onboard voltage translator compatible with 3.3V / 5V MCUs. No backlight, with image retention after power-off. Ultra-low power consumption, with power mainly required during refresh. Comes with development resources and examples for Raspberry Pi, Jetson Nano, Arduino, STM32, and other controllers.

Asset and equipment tags. Conference name tags and information cards. Industrial instruments and status displays. Warning labels, notice panels, and alert signage. Large-format tri-color SPI e-paper development with Raspberry Pi, Jetson Nano, Arduino, and STM32. Packing List 13.3inch e-Paper (B) x1 e-Paper Driver HAT + Adapter board + FFC cable x1 RPi screws pack (2pcs) x1 GH1.25 9PIN cable ~20cm x1 Other Content Why the tri-color panel mattersThe added red channel makes this module more suitable for signage and label applications where you need color emphasis for prices, warnings, categories, or status highlights, without moving to a more complex full-color display technology. Best-fit projectsThis display is especially suitable for projects that need a large paper-like interface with ultra-low power consumption, static image retention, and a simple red / black / white visual hierarchy. That makes it a strong fit for shelf labels, warning boards, industrial signage, and information panels. Pin referenceThe control pins are VCC, GND, DIN, CLK, CS, DC, RST, BUSY, and PWR, which makes this HAT straightforward to integrate into Raspberry Pi, Jetson Nano, Arduino, and STM32 projects. Resources Waveshare Wiki Manual 13.3inch e-Paper (B) Specification GitHub Demo Repository Schematic FAQ What makes this display different from the black-and-white 13.3 inch version? The main difference is that this model is a 3-color e-paper panel with red, black, and white output, making it more suitable for signs, price tags, and warning information where highlight color matters. What is it best used for? It is especially suitable for price tags, shelf labels, warning signage, asset tags, conference name tags, and low-power information displays. Does it need constant power to keep the image? No. Like other e-paper displays, it keeps the last image visible after power-off. What is included in the package? The package includes 13.3inch e-Paper (B), e-Paper Driver HAT + Adapter board + FFC cable, RPi screws pack (2pcs), and GH1.25 9PIN cable ~20cm.
