Waveshare 4.2inch e-Paper Module (B) is a three-color E-Ink display module with 400 x 300 resolution, an embedded controller, and SPI communication. It displays red, black, and white, making it useful for clear low-power information panels, labels, embedded status screens, and controller-based display projects.
The module supports 3.3V to 5V operation, 3-wire SPI, and 4-wire SPI. E-Paper technology keeps the last screen content visible without continuous power, while power is mainly required during refresh. The official reference lists a 15s full refresh time, 26.4mW typical refresh power, <0.017mW standby power, and a >170 viewing angle.

It displays red, black, and white, with a 2-level grey reference.
The display resolution is 400 x 300 pixels on a 4.2inch E-Paper panel.
It communicates through SPI and supports 3-wire SPI or 4-wire SPI setups.
No continuous power is needed to keep the last displayed content visible, but stable power is required when refreshing the image.
No. The official full-refresh reference is 15s, so this module is better for low-power information displays that update occasionally.
