===Teensy as a keyboard controller===
There are DIY keyboard projects where a Teensy is used as a controller:
* The [[Phantom]] is a tenkeyless keyboard that uses the smaller Teensy 2.0 as controller chip.
* The [[ErgoDox]] is a split column-layout keyboard project with a Teensy 2.0 in one half and an I/O expander in the other half.

The "Teensies" have also been used as a controller for [[Controller matrix traces|existing keyboard matrices]], such as, when a keyboard's protocol is deprecated and/or the keyboard has been cut down into a smaller matrix.
The Teensy 2.0 (with only 25 I/O lines) may be enough for a compact keyboard.
Most keyboards with 101 keys or more have larger, more sparse matrices where the larger Teensy++ would be a better choice. Sparser matrices are more common in keyboards that don't have diodes, as holes in the matrix may be used to avoid blocking of certain key combinations.
