[posted] Teensy Thumb Keyboard

[anthonysavatar]

Hi all! Here is a breakout board I put together in the shape of a thumb keyboard for the Teensy 3.2.



Features

• Beginner friendly through hole soldering.
• 60 keys arranged in a familiar qwerty layout with number keys arranged in a numpad.
• SPI, I2C, and 2 additional GPIOs broken out. Aside from these pins all others are used to read the key matrix.
• Teensy can be rotated with the micro USB facing up or down. Breakout pins will only work as expected with USB facing up.

I'm still waiting on a rev v1.1 board and will update when that arrives. Code is working but it needs some cleanup before I can share.

Cool. Looks like a really nice little keyboard
