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 April 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.
