    [posted] Teensy Thumb Keyboard

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

    • 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.

    Lots of photos available at:

    KiCad and STLs:

    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.
