2.7 inch E-paper Display

Embedded Artists' 2.7 inch E-paper Display module adds graphics capabilities to your project.

The module use the EM027AS012 from Pervasive Displays.
The EM027AS012 display is also sold separately (for own designs).

The display has an SPI interface and some extra control signals. The display module connects to Embedded Artists' standard 14-pos expansion connector. Several of our products have the connector on-board. More modules are found here.

Technical details about how to interface the display can be found on the RePaper site.

Specification

2.7 inch E-paper Display Module

  • Based on display EM027AS012 from Pervasive Displays
  • 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°
  • No backlight - display useful in daylight applications
  • SPI interface + control signals, incl a PWM signal
  • Diagonal size: 2.7 inch
  • Module supply voltage: 3.3V, the display is supplied with 3.0V via on-board LDO
  • View area: 57.3 × 38.2 mm
  • Operating temperature: 0 to +50 degrees Celsius
  • No of colors: 2 (blackr and white)
  • Standard 14 pos serial expansion connector interface (2x7 shrouded pin header, 50/100 mil spacing)
  • 60 x 74 mm module size
  • 3.2 mm mounting holes in 52 x 66.3 mm pattern

Supported Boards

The 2.7 inch E-paper Display Module can be used directly with any of the following Embedded Artists boards:

  • OEM Base Board - included in the LPC1788 / LPC4088 / LPC3250 Developer's Kit.
  • AOA Application Kit

It is simple to interface the standard 14-pos serial expansion connector with any custom design.
