Advantages Of EINK

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.

Optional For E-Paper Driver Board

Onboard SPI Control Interface, For Use With Controller Boards Like Raspberry Pi / Jetson Nano / Arduino / STM32

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 (high for data, low for command)
RST	External reset, low active
BUSY	Busy status output pin

Onboard Voltage Translator

Compatible With 3.3V / 5V MCUs

Application Examples

Suitable For Price Tags, Asset/Equipment Tags, Shelf Labels, Conference Name Tags...
