1.9 inch Segment E-Paper Module

A 1.9" e-paper segment display consisting of 91 segments . The passive reflective screen is able to display a black and white image, the viewing angle is over 170 °. It uses the I2C interface for communication. E-paper screens are characterized by very low power consumption, basically energy is only required for refreshing The module supports partial refreshing, the time of which is 0.3 s Segment e-paper displays are perfect for displaying values from temperature and humidity sensors , air humidifiers, etc. Module works with a voltage of 3.3 V and 5 V.

Main features of segmented e-paper screen

• No backlight, it displays the last content for a long time, even when the power is disconnected
• Very low power consumption, power only required for refreshing
• I2C interface, compatible with Arduino , Raspberry Pi , STM32 , etc.
• Built-in MOS voltage regulator, 3.3 V and 5 V power supply

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
