This board configuration can also be used with the older Teensy-3.0. The
Teensy-3.0 has the same schematic (although some pins are not used on the
Teensy-3.0). the primary difference is that the Teensy 3.0 has a
MK30DX128VLH5 with slightly less capability.

between the MK30DX256VLH7 and the MK30DX128VLH5 but the basic differences
