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.

PJRC intends to continue production of Teensy 2.0. We have sufficient inventory to keep Teensy 2.0 available until at least May 2021, assuming sales continue at the 2018-2020 rate. We do expect to discontinue Teensy 2.0 and Teensy++ 2.0 sometime in 2021 or 2022. 32 bit Teensy boards are recommended for new projects.
