This is the port of NuttX to the PJRC Teensy++ 2.0 board. This board is
developed by http://pjrc.com/teensy/. The Teensy++ 2.0 is based
on an Atmel AT90USB1286 MCU.
This is the port of NuttX to the Teensy-3.1 from PJRC
(https://www.pjrc.com/). The Teensy-3.1 features the Freescale
MK30DX256VLH7 chip (now NXP). The MK30DX256VLH7 is a 64-pin Cortex-M4
running at 72MHz. It has 256KiB of program FLASH memory and 64KiB of
SRAM. For more information about the Teensy 3.1, see
https://www.pjrc.com/teensy/teensy31.html
https://www.pjrc.com/store/teensy31.html
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.
