Teensy
Teensy is a family of small, breadboard-friendly USB microcontroller development boards designed by PJRC. They pack fast 32-bit ARM processors into a tiny footprint and are programmed with the familiar Arduino IDE using the Teensyduino add-on, so most Arduino code and libraries work with little or no change.
Teensy boards are a favourite for projects that need more speed than a classic Arduino: audio processing and synthesisers, USB MIDI controllers, custom keyboards and game controllers, LED art, robotics and data logging.
