Advantages Of E-INK
E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.
Onboard SPI Control Interface
For Connecting With Controller Boards Like Raspberry Pi/Jetson Nano/Arduino/STM32
| VCC | 3.3V/5V |
| GND | Ground |
| DIN | SPI MOSI pin |
| CLK | SPI SCK pin |
| CS | SPI chip selection, low active |
| DC | Data / Command selection (high for data, low for command) |
| RST | External reset, low active |
| BUSY | Busy status output, low active |
Onboard Voltage Translator
Compatible With 3.3V / 5V MCUs
Application Examples
Suitable For Price Tags, Asset/Equipment Tags, Shelf Labels, Conference Name Tags...

Is this module compatible with common microcontrollers such as Raspberry Pi or Arduino?
Yes. It uses a 3-wire or 4-wire SPI interface and includes an onboard voltage translator compatible with 3.3V and 5V MCUs, making it suitable for Raspberry Pi, Jetson Nano, Arduino, STM32, and similar boards.
Does the display require a backlight and what about power use when idle?
No backlight is required; it is a passively reflective display that retains the image without power. It draws ultra low power and only consumes energy when refreshing the SPI interface, with standby current below 0.01uA.
What are the main specifications such as size, resolution, colors, and interface?
The module is 2.9 inches with 296 x 128 resolution, display colors red black white, grey scale 2, and uses a 3 wire or 4 wire SPI interface with an onboard voltage translator that supports 3.3V and 5V MCUs.
What is the full refresh time and refresh power?
Full refresh time is 15 seconds and refresh power is 30 mW typical.
What are common use cases for this e paper module?
Ideal for price tags, shelf labels, asset and equipment tags, conference name tags, and other labeling and industrial instrument applications.
