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

Standard Raspberry Pi 40PIN GPIO header, compatible with Raspberry Pi series boards, Jetson Nano

3.97inch e-Paper with driver board, Standard Raspberry Pi 40PIN GPIO header

* for reference only, the Raspberry Pi is NOT included.

Onboard SPI control interface

for use with controller boards like Raspberry Pi/Jetson Nano/Arduino/STM32

PWR	Power on/off control
BUSY	Busy status output pin
RST	External reset, low active
DC	Data/Command selection (high for data, low for command)
CS	SPI chip selection, low active
SCLK	SPI SCLK pin
DIN	SPI MOSI pin
GND	Ground
VCC	Power (3.3V / 5V input)
