 # Teensy: development platform for [PlatformIO](http://platformio.org)

+[![Build Status](https://github.com/platformio/platform-teensy/workflows/Examples/badge.svg)](https://github.com/platformio/platform-teensy/actions)
 
 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 USB cable and a PC or Macintosh with a USB port.
