-This is where you choose which architecture you want to build for.
-The options are:
- - Teensy 1.0   (Not tested)
- - Teensy 1.0++ (Not tested)
- - Teensy 2.0
- - Teensy 2.0++
- - Teensy 3.0
- - Teensy 3.1
+This is where you select the chip you want to compile for.
+The build system will automatically select the compiler needed to compile for your chip.
