3.52inch 3 Color E-Paper Display (B)
3.52inch e-Paper display with 360 240 resolution, red / black / white display color, SPI interface, low power consumption, and optional driver board support.
Designed for price tags, shelf labels, industrial instruments, asset labels, conference name tags, and other low-power display applications.
Key Features
- 3.52inch e-paper display with 360 240 resolution and red / black / white three-color output.
- No backlight; the screen keeps displaying the last content for a long time even after power is removed.
- Ultra-low power consumption, with power mainly required during refresh.
- Wide viewing angle and paper-like visual effect under ambient light.
- SPI communication interface for controller boards such as Raspberry Pi, Jetson series, RDK X3, Arduino, and STM32.
- Optional driver board provides Raspberry Pi 40PIN GPIO header and onboard voltage translator for 3.3V / 5V MCUs.
Version Options
3.52inch e-Paper (B)
Raw display version without driver board.
3.52inch e-Paper HAT (B)
Version with driver board.

E-Paper Advantages
E-paper display uses microcapsule electrophoretic technology. Charged particles suspended in clear fluid move when an electric field is applied, making the display visible by reflecting ambient light like printed paper.
The display is clearly visible under lamplight or natural light, requires no backlight, and provides a paper-like viewing experience with a wide viewing angle.
Raspberry Pi 40PIN GPIO Header
The optional driver board uses a standard Raspberry Pi 40PIN GPIO header and is similar in size to Raspberry Pi boards, supporting Raspberry Pi 5 / 4B / 3B / 3B+ form factors.
Optional Driver Board Interface
The driver board provides an onboard SPI control interface for use with Raspberry Pi, Arduino, STM32, and similar controller boards.
| VCC | Power, 3.3V / 5V input |
|---|---|
| GND | Ground |
| DIN | SPI MOSI pin |
| CLK | SPI SCK pin |
| CS | SPI chip selection, low active |
| DC | Data / Command selection |
| RST | External reset, low active |
| BUSY | Busy status output pin |
Onboard Voltage Translator
The optional driver board includes an onboard voltage translator, making it compatible with 3.3V / 5V MCUs.
Application Examples
Suitable for price tags, asset and equipment tags, shelf labels, conference name tags, and other compact low-power display applications.
