Teensy 3.2 is officially discontinued. However, they are still very useful for projects requiring more computing power! We are selling our remaining stock at cost.

From Adafruit:

Teensy 3.2 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC. Teensy 3.2 brings a low-cost 32 bit ARM Cortex-M4 platform to hobbyists, students and engineers, using an adapted version of the Arduino IDE (Teensyduino) or programming directly in C language. Teensy 3.2 is an upgrade over 3.1! Teensy 3.2 is a drop-in replacement upgrade for 3.1 and can run any sketches designed for 3.1.

This latest version of this complete USB-based microcontoller development system now adds a more powerful 3.3V regulator, as well as accepts a wider voltage input range. This board has the same size, shape and pinout as well as full compatibility with all shields and add-on boards made for the Teensy 3.1, plus double the Flash memory as the Teensy 3.0.

Let’s get started!

Please note: Teensy 3 and 2 are not official Arduino-brand products. Although the Teensyduino IDE has been adapted so that many simple Arduino projects will work with the Teensy, there will still be a lot of libraries and shields that will not work with this device! If you’re new to microcontrollers, we suggest going with a classic Arduino UNO since all Arduino projects, examples and libraries will work with it.

Once headers are installed they can be fitted into 0.6″ wide sockets
