Description
Waveshare 7.5inch E-Paper Module (B) for Pico is a large-format red, black, and white e-paper display designed for use with the Raspberry Pi Pico ecosystem. It combines an 800 × 480 resolution panel with a dedicated Pico e-Paper driver board, making it suitable for price tags, shelf labels, industrial indicators, equipment tags, conference signage, and low-power information displays.
The display uses the natural advantages of e-paper technology: no backlight, wide viewing angle, and the ability to retain the last image after power-off. Power is mainly consumed during refresh, which makes it a strong fit for battery-powered or always-visible embedded applications.
Features
- 7.5 inch e-paper display with 800 × 480 resolution.
- Red, black, and white display colors for clear low-power signage and status output.
- No backlight, with a paper-like viewing experience and retained image after power loss.
- Ultra-low power consumption, with power mainly required during refresh.
- SPI interface with minimal IO requirement.
- Designed for Raspberry Pi Pico with dedicated driver board and Pico header compatibility.
- 2 user buttons and 1 reset button for direct hardware interaction.
- Development resources for Pico, including C/C++ and MicroPython examples.

Other Content
The Pico-ePaper-Driver-Board adds practical integration features beyond the raw panel itself. It provides a dedicated interface for the e-paper display, direct Raspberry Pi Pico header compatibility, and onboard buttons that make development and testing easier.
E-paper technology is especially useful where the screen content changes infrequently but must remain visible all the time. That is why this 7.5inch e-paper module for Pico is a practical option for signage, labels, and low-power embedded display systems.
