Over the last couple weeks I’ve been working on a automated test system for Teensyduino, which someday will verify nearly all the Arduino functionality on every board and also test most of the Arduino libraries. Here’s what my first try looks like.
The Teensy 2.0 is a complete USB-based microcontoller development system, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard “Mini-B” USB cable and a PC or Macintosh with a USB port.
