  • Outline dimension (Driver board): 51 × 34 mm
  • Display size: 41.35 × 28.11 mm
  • Operating voltage: 3.3V/5V
  • Interface: IIC
  • Segment code: 91-segments
  • Display color: black, white
  • Gray scale: 2
  • Partial Refresh: 0.3s
  • Full refresh time: 2s
  • Refresh power: <5mW(typ.)
  • Standby current: <0.01uA (close to 0)
① Refresh time: The refresh time is the experimental test data, the actual refresh time will have errors, and the actual effect shall prevail. There will be a flickering effect during the global refresh process, this is a normal phenomenon
② Power consumption: The power consumption data is the experimental test data. The actual power consumption will have a certain error due to the existence of the driver board and the actual use situation. The actual effect shall prevail.

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.

I2C Control interface

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

VCC3.3V / 5V
SDAI2C Communication data pins
SCLI2C Communication clock pin
RSTExternal reset pin (low reset)
BUSYBusy status output pin (high level means busy)

Application Examples
Suitable for temperature and humidity meters, humidifiers, power meters, etc.
