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.\n\nThe 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.\n\nKey Features\n\n\nFour-Colour Display – Red, yellow, black, and white for vivid static content\n\n800×480 Resolution – Sharp detail with 0.204 × 0.204 mm dot pitch\n\nUltra-Wide Viewing Angle – Over 170° for clear visibility from any direction\n\nUltra-Low Power – Power required only during refresh; image persists without power\n\nSPI Interface – 3-wire or 4-wire SPI for broad microcontroller compatibility\n\nPaper-Like Display – Reflective technology, no backlight needed\n\n22-Second Full Refresh – Complete content update cycle\n\n\nSpecifications\n\n\nDisplay Size: 7.5\" (163.20 × 97.92 mm active area)\n\nResolution: 800×480\n\nColours: Red, yellow, black, white\n\nGrey Scale: 2 levels\n\nInterface: 3-wire SPI, 4-wire SPI\n\nOperating Voltage: 3.3V (raw display), 3.3V/5V (with driver HAT)\n\nDot Pitch: 0.204 × 0.204 mm\n\nRefresh Time: 22 s\n\n\n\nNote: An e-Paper Driver HAT is required but sold separately.
