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 purchases scheduled with Atmel sufficient to keep Teensy++ 2.0 available until at least December 2019, assuming sales continue at 2017's rate. This doesn't necessarily mean we will discontinue Teensy 2.0 in 2019. That's a decision we'll consider in mid 2019. We understand many people use these older 8 bit products. While we can't make an absolute gaurantee of future availability, we can tell you we're planning to continue production of Teensy++ 2.0.
