2.7 inch E-paper Display - Revision D

RETIRED PRODUCT - We've stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.

E-paper - the ultimate low power display solution! Add a 2.7" graphic display to your project that doesn't need any power to stay on, with this fully bi-stable E-paper display you only need to supply power when updating the display.

The display has an SPI interface and some extra control signals. The display module connects to a standard 14-pos expansion connector.

Revision D now includes a 26 pin Raspberry Pi connector, LM75 I2C temperature sensor and a 32Mbit SPI-NOR Flash chip!

• Based on display EM027BS13
• a-Si, active matrix TFT, Electronic Paper Display (EPD) panel
• No of pixels: 264x176
• High resolution - 117 dpi (0.217 x 0.217mm pixels)
• Ultra low power consumption - due to its bi-stable nature, the EPD panel requires very little power to update the display and needs no power to maintain an image
• Very wide viewing angle - near 180

• RePaper GitHub - Libraries and Examples
• E-paper Display Module - Rev C (improved version with possibility for separate SSEL signals for SPI FLASH and display)
• Technical details about how to interface the display can be found on the RePaper site
