The Teensy++ USB Development Board is a comprehensive USB microcontroller development system that requires only a standard Mini-B USB cable (sold separately) for connecting to a computer. This model comes with header pins to easily plug into a solderless breadboard; alternatively, the Teensy board can be obtained without these pins. All Teensy boards are shipped preassembled and thoroughly tested. To interface this board with your PC for CNC control panel usage, you can download the software from the provided website (not created nor sold by me).
