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.
Compatible With Raspberry Pi Series Boards, Jetson Nano
For Use With Other Controller Boards Like STM32/Ard
| VCC | 3.3V/5V |
| 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, high active |
Suitable For Price Tags, Asset/Equipment Tags, Shelf Labels, Conference Name Tags...
