Mantis Q40 braille display

The first–of–its–kind integrated keyboard and refreshable braille display

The Mantis Q40 is the first-ever Bluetooth® QWERTY keyboard and 40-cell refreshable braille display that you can pair with your screen reader or smartphone or simply use as a standalone device. Either way, you have braille at your fingertips, every time.


Absolutely love my new Mantis Q40. Having the qwerty keyboard and braille makes it so user friendly for everything from reading books to using for work.

Another use for the excellent Mantis Q40! …I used it to log in via SSH through prompt on my phone to my VPS. Having braille makes it easier to keep track of larger directories and ensure the right operators are entered.

I like the Mantis Q40. Forty cells of braille, qwerty keyboard so you don’t have to learn a separate set of screen reader command.
