This 7.5" e-paper display (H) features 800×480 resolution with a four-colour palette of red, yellow, black, and white. Using microcapsule electrophoretic technology, it delivers a paper-like viewing experience with natural light reflection, an ultra-wide >170° viewing angle, and zero power consumption between refreshes.
The display communicates via 3-wire or 4-wire SPI interface and operates at 3.3V (or 3.3V/5V with an optional driver HAT). It's suitable for static image applications where clarity and low power are essential.
Key Features
- Four-Colour Display – Red, yellow, black, and white for vivid static content
- 800×480 Resolution – Sharp detail with 0.204 × 0.204 mm dot pitch
- Ultra-Wide Viewing Angle – Over 170° for clear visibility from any direction
- Ultra-Low Power – Power required only during refresh; image persists without power
- SPI Interface – 3-wire or 4-wire SPI for broad microcontroller compatibility
- Paper-Like Display – Reflective technology, no backlight needed
- 22-Second Full Refresh – Complete content update cycle

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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.
