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.

Standard Raspberry Pi 40PIN GPIO header

compatible with Raspberry Pi series boards

VCC 3.3V/5V
GND GND
DIN SPI MOSI pin
CLK SPI SCK pin
CS SPI chip selection, low active
DC Data / Command selection (high for data, low for command)
ERST External reset, low active
BUSY Busy status output, high active
INT Touch controller interrupt pin
SCL Touch controller I2C clock pin
SDA Touch controller I2C data pin
TRST Touch controller reset, low active
EN Touch control power supply enable (optional), high active
Touch control power supply configuration

the touch control power supply is determined by the position of 0R resistor

0R resistor position touch control power supply Description
A VCC always powered by VCC (default)
B EN controlled by user I/O
C VEN controlled with ePaper (ERST)
NC GND no power supply for touch control
