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.

SPI Control Interface

For Use With Controller Boards Like Raspberry Pi / Arduino / STM32

VCC3.3V / 5V
CSSPI chip selection, low active
DCData / Command selection (high for data, low for command)
RSTExternal reset, low active
BUSYBusy status output, high active(High level indicates busy)

Onboard Voltage Translator
Compatible With 3.3V / 5V MCUs
