Pervasive Displays e-Paper Screens

E-paper screens only require power to change the display. Otherwise, they need no power supply: this feature makes them the ideal solution for ultra-low-power applications.

Pervasive Displays offers a wide range of e-paper screens, with two colours in black and white, three colours in black-white-red or black-white-yellow, or four colours black-white-red-yellow.

A new version of the 2.71" monochrome screen offers fast display, more than 3.5 times faster, reviewed at Pervasive Displays e-Paper Screen with Fast Update.

Pervasive Displays E-Paper Display Kit for Matter (EPDK-Matter)

The Pervasive Displays E-Paper Display Kit for Matter (EPDK-Matter) bundles the EXT4 extension board and a 2.90" high definition screen with an Arduino Nano Matter to explore the Matter protocol.

The Silabs core for Arduino provides the Matter library and the Pervasive Displays Library Suite manages the screen and the sensors.

Two examples leverage the Matter protocol: a weather station and a RGB LED.

Pervasive Displays E-Paper Display Pico Kit Touch (EPDK-Touch)

The Pervasive Displays E-Paper Display Pico Kit Touch (EPDK-271-Touch) adds touch to the e-paper technology to explore ultra-low power human-machine interfaces.

On the software side, the Pervasive Displays Library Suite has been updated for Arduino and is also available for Python.

Pervasive Displays E-Paper Display Pico Kit

The Pervasive Displays E-Paper Display Pico Kit (EPDK) includes everything to start exploring the e-paper technology, including the popular Raspberry Pi Pico board.

Boards

EXT4

The Pervasive Displays e-Paper EPD Extension Kit Gen 4 (or EXT4) adds a large choice of sensors to the screen driver circuit and combines them into a signal board.

The sensors include a 3-axis accelerometer, a temperature and relative humidity sensor, a button, an RGB LED, and a passive NFC antenna. The sensors are driven through I²C and all the interrupt signals are exposed.

EXT3-1 and EXT3-Touch

The last revision of the EPD Extension Kit Gen 3-1 comes with an expansion board for touch and brings a whole new dimension to e-paper displays.

Instead on being passive devices, e-paper displays are now active input devices, perfectly suited for ultra-low power human-machine interfaces.

Connecting the e-Paper EPD Extension Kit Gen 3-1 is as easy as counting from 1 to 10.

Assembing the Pervasive Displays EXT3-Touch requires four more connections, thus counting up to 14.

Pervasive Displays Library Suite

The Pervasive Displays Library Suite is specifically designed for the Pervasive Displays screens and boards.

It provides a high-level interface to drive the e-paper screens with global and fast update, supports capacitive touch and haptic feed-back.

It is developed in C++ and relies on the Arduino SDK. It could easily be ported to any other SDK.

The User guide focuses on how to use the different libraries, with commented examples. The Reference manual lists all the objects and functions, with details for their parameters and returned results.
