A recent batch of Teensy 2.0 boards had slightly discolored USB connectors. They have passed all testing, including programming the LED blink by USB, and they work perfectly fine.

While they last, we're offering these boards at half price!

Sorry, Sold Out

Teensy USB Board, Version 2.0

Plenty of the normal Teensy 2.0 boards are in stock. Even the regular $16 price is lower than all other Arduino and Arduino-like boards. Hopefully you'll consider Teensy for a future project?

A few months ago we switched to a different USB connector with much higher quality metal and plating. All normal Teensy 2.0 shipping since March 2012 have these higher quality USB connectors.

Limit 2 per person.

The Teensy USB Development Board is a complete USB-based microcontoller development system. Only a standard Mini-B USB cable (sold separately) is needed to connect to a PC or Macintosh.

This version has solder pads for all I/O signals. The Teensy is also available with the header pins to plug directly into a solderless breadboard.

All Teensy boards are shipped assembled and fully tested.
