e-paper technology.

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 eyesight does not get tired so much during use, and reading is even more enjoyable than before.

• No backlight, it displays the last content for a long time, even when the power is disconnected
• Very low power consumption, power only required to refresh the image
• SPI interface, compatible with Arduino , Raspberry Pi , STM32 , etc.
• Built-in voltage regulator compatible with 3.3V/5V boards

At the back of the display there is a connector with leads, so there is no need to solder the connectors. Just connect the display using the cable included in the set in accordance with the following relationships:

• VCC - supply voltage
• GND - system ground
• DIN - MOSI line of the SPI bus
• CLK - SCK line of the SPI bus
• CS - chip select (activated low)
• DC - data / command selection pin (high state for data, low state for commands)
• RST - reset, activated by low state
• BUSY - output pin of the busy state, activated high

On the back of the display there is a connector with leads.

The screen has a square shape with a diagonal of 1.64''.
