Update: Due to limited chip supply for Teensy 3.x, PJRC is discontinuing pins soldering for all Teensy 3.x products. As we are able to get the chips, we'll continue making these boards without the pins soldered.

Actual size is 1.4 by 0.7 inch

The Teensy USB Development Board is a complete USB-based microcontoller development system.

Teensy 3.2 is a direct, 100% compatible replacement for Teensy 3.1. It is fully compatible with all shields and add-on boards made for Teensy 3.1, including the Audio Board and OctoWS2811 Adaptor.

All Teensy boards are shipped assembled and fully tested.
