  • I2C interface, compatible with Arduino , Raspberry Pi , STM32 , etc.
  • Built-in MOS voltage regulator, 3.3 V and 5 V power supply

The manufacturer has prepared a detailed guide for Arduino, Raspberry Pi and STM32 users with connection examples and program codes.

What is the "e ink e paper" display?

The e-paper display, also known as e-paper display, uses electrophoretic microcapsule technology to present data. This means that it mimics the appearance of standard ink found on traditional paper. This type of technology is extremely user-friendly - screens do not emit blue glow, are passively reflective and provide a wide viewing angle. All these features mean that our eyes do not get tired so much during use, and reading is even more enjoyable than before.

Pins of the e-Ink display module

The e-paper display module uses the I2C interface to communicate with the microcontroller. Thanks to the applied voltage regulator, it can be powered with 3.3 V or 5 V.

  • VCC - supply voltage
  • GND - system ground
  • SDA - data line of the I2C bus
  • SCL - clock line of the I2C bus
  • RST - reset, activated by low state
  • BUSY - output pin of busy state, activated by high state

e-paper display specification

  • Supply voltage: 3.3 V or 5 V
  • Interface: I2C
  • Number of segments: 91
  • Display color: black and white
