Pi Supply has achieved Kickstarter funding for a “Papirus” display HAT that supports E-paper displays up to 2.7 inches on the Raspberry Pi and other SBCs.
Like Percheron Electronics’s recent E-Paper HAT Display, Pi Supply’s Papirus is a Raspberry Pi HAT (Hardware Attached on Top) form-factor add-on board available with a variety of under 3-inch E-paper displays from Pervasive Displays. Kickstarter packages available through June 5 are priced lower than the Percheron E-Paper HAT Kickstarter packages.

Although it’s optimized for the Raspberry Pi Model A+, B+, and new Pi 2 Model B, the Papirus works with any hacker board that runs on 3V or 5V logic and power, and that includes I2C and SPI interfaces, says Pi Supply. These include Arduino, BeagleBone, and upcoming $9 Chip SBCs, among others, says the company.
The Papirus offers the same three Pervasive Display options provided with Percheron’s E-paper HAT. The options are listed below with their lowest currently available Kickstarter prices, which include the Papirus HAT board:
- 1.44-in., 128 x 96 pixels — 25 Pounds ($39)
- 2.0-in., 200 x 96 pixels — 28 Pounds ($44)
- 2.7-in., 264 x 176 pixels — 35 Pounds ($55)

Other features available on the Papirus include:
- 32Mbit flash
- Battery-backed RTC (CR2032 battery included)
- EEPROM for “easy plug and play”
- Digital temperature sensor and thermal watchdog
- GPIO breakout connector and solder pads with optional GPIO breakout board
- Optional reset pin header (for wake on alarm with RTC)
- 4x optional slim-line switches on top
- Optional pogo pin
The Papirus has so far earned about $36,000, or about five times its Kickstarter project’s goal. If Pi Supply reaches $45,000, the company will fulfill a new stretch goal by adding “some enhanced software above and beyond what is included in the free rePaper offering from Pervasive Displays,” says Pi Supply. Planned software are said to include an “easy installer” and many more example scripts, including one to push the Raspbian desktop to the ePaper screen. One possibility is to add a web app for remote screen management.
The Papirus is available through June 5 on Kickstarter at the prices shown above. Bundled discounts are also available. Shipments are expected in July. More information may be found at the Papirus Kickstarter page, and information should eventually appear on the Pi Supply website.
