We have started to develop a basic refreshable braille display.
Main goal : build an open hardware with open source driver.
Our prototype is today based on a Arduino mainboard driving proprietary braille cells.

The prototype should provides following elements :

• USB and Bluetooth interfaces
• Braille refreshable cells (any number)
• Joystick and buttons for navigation
• LEDs matrix display for easy development
• Haptic force
• Microcontroller simple code
• BrlTTY and libbraille drivers
• Adapted case
