Platform ``teensy``
===================

`Teensy <https://www.pjrc.com/teensy/>`_ is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port.
