Teensy 3.2 USB Board


The 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 "Micro-B" USB cable and a computer with a USB port.

To use the Teensy on a breadboard, you will need to add the optional header pins. The Teensy can also be run from the +5VDC on a USB cable.
