Capacitive Touch Display E-paper E-Ink - 2.9'' 296x128px - SPI/I2C - black and white - for Raspberry Pi - Waveshare 19967

Touchscreen display made by Waveshare ine-papertechnologywith diagonal of2,9'' and resolution of 296x 128 px. The screen works with any 40-pin version ofRaspberry Pi, and can also be used with Arduino and STM32. The image is displayed in two colors: black and white. The module usesSPIandI2Cinterfaces for communication. The e-paper technology makes this type of display suitable for use in e-book and electronic magazine readers.

Touchscreen e-paper display for Raspberry Pi. The item for sale is the e-paper display, the Raspberry Pi minicomputer can be purchased separately.

• 2.9" screen with 296 x 128 px resolution and capacitive touch
• Supports 5 touch points, user-defined screen wake-up gesture
• No backlight, retains last displayed image for long time after power disconnection
• Ultra low power consumption, power is only required to refresh the screen
• SPI / I2C interface
• Works with any 40-pin version of Raspberry Pi
• Also works with boards like Arduino and STM32

The e-paper displays work based on electrophoretic microcapsule technology: charged particles suspended in a transparent liquid move to the sides of the microcapsule when an electric field is applied, making the microcapsule visible by reflecting ambient light, just like traditional printed paper. The e-paper display clearly displays images/text in lamplight or natural light, requires no backlight, and has a viewing angle of nearly 170°. This type of display is usually used in e-book readers because of its paper-like effect.

A display module in the form of an overlay for direct connection to a Raspberry Pi. It uses pins like:

• VCC - supply voltage 3,3 V / 5 V
• GND - ground
• DIN - MOSI pin of SPI bus
• CLK - pin SCK of SPI bus
• CS - SPI chip selection, activated by low state
• DC - data / commands pin (high for data, low for commands)
• ERST - external reset, activated by low state
• BUSY - busy state output, activated with high state
• INT - touch controller interrupt pin
• SCL - touch controller I2C bus clock pin
• SDA - touch controller I2C bus data pin
• TRST - touch controller reset, activated by low state
• EN - power supply activation for the touch controller (optional), activated by a high state
