This 2.15inch E-Paper Display (B) features a 296x160 pixel resolution with red, black, and white color support, delivering clear and sharp text, symbols, and simple graphics. Ideal for electronic labels, shelf tags, and low-power information panels. E-ink technology only consumes power during refresh, enabling ultra-low standby power usage. Once the content is refreshed, the display image can be retained for a long time without continuous power supply, making it perfect for battery-powered and energy-saving applications. Standard SPI interface ensures simple and reliable communication with mainstream development boards. It is compatible with common 3.3V logic MCUs and can be driven by platforms such as Arduino, Raspberry Pi, STM32, and other microcontrollers with SPI support. Supports partial refresh to update only a specific area of the screen, effectively speeding up refresh time and reducing flicker compared with full-screen refresh. This is especially useful for frequently changing data such as prices, counters, and simple UI elements. Suitable for electronic shelf labels, price tags, industrial instruments, smart home panels, information displays, and portable devices. The tri-color (red/black/white) display helps highlight key information such as discounts, warnings, or important notifications.
