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 Board

Reversed Control Interface
I2C Bus For Touch Panel, SPI Bus For Display
| 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 |

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 |
