Advantages of E-Ink Screen

The electronic ink screen uses "microcapsule electrophoresis display" technology to display images. Its working principle is that charged nanoparticles suspended in liquid migrate under the action of the electric field, and form a display effect close to traditional printed paper through reflection under ambient light. The electronic ink screen can display images clearly under ambient light such as light and natural light, without backlight, and the viewing angle is almost 180°. Because its display effect is comparable to that of traditional paper, it is often used in applications such as readers.

Reserved SPI control interface

Can be connected to Raspberry Pi / Jetson Nano / Arduino / STM32 and other main control boards

PWR	Power on/off control pin
BUSY	Busy status output pin
RST	External reset pin (low level reset)
DC	Data/command control pin (high level indicates data, low level indicates command)
CS	SPI chip select pin (active low)
SCLK	SPI Communication SCLK Pin
DIN	SPI communication MOSI pin
GND	GND
VCC	3.3V / 5V

Onboard level conversion chip

Compatible with 3.3V and 5V level interfaces

Application Scenario

Applicable to shopping mall price tags, asset equipment labels, electronic shelf labels and conference name tags, etc.
