Frequently asked questions
Is the Teensy++ 2.0 an Arduino board?
It is not a stock Arduino board, but it can be programmed from the Arduino IDE after installing Teensyduino. Its pin layout differs from Arduino Uno-style boards, so check the pinout before reusing shields.
How is the board programmed?
It is programmed over USB using the Teensy loader, which is integrated with Teensyduino in the Arduino IDE, so no separate hardware programmer is needed for uploads.
