Hi all! Here is a breakout board I put together in the shape of a thumb keyboard for the Teensy 3.2.
Features
Lots of photos available at: https://hackaday.io/project/162281-teensy-thumb-keyboard
3D Model of a Raspberry Pi Handheld Proof of concept Project: https://www.thingiverse.com/thing:3209958
KiCad and STLs: https://github.com/AnthonyDiGirolamo/teensy-thumb-keyboard
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.
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.
