Teensy 3.2 (With Pins)

The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. The Teensy 3.2 brings a 32 bit ARM Cortex microprocessor into the mix so you can do some serious number crunching. The Teensy 3.2 comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed!

You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy! The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects.

The 32 bit processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access, several high-resolution ADCs and even an I2S digital audio interface! There are also 4 separate interval timers plus a delay timer! Oh yeah, and all pins have interrupt capability. Also, it can provide system voltage of 3.3V to other devices at up to 100mA. All of this functionality is jammed into a 1.4 x 0.7 inch board with all headers on a 0.1″ grid so you can slap in on a breadboard and get to work!

On top of everything else the Teensy has been gifted with more RAM (64K, thats 4x more than the Teensy 3.0) and 256kb of flash memory! The Teensy 3.2 now now has 5V tolerance on its digital inputs however all analog-only pins are still 3.3V only. Teensy 3.2 adds a more powerful 3.3 volt regulator, with the ability to directly power ESP8266 Wifi, WIZ820io Ethernet and other power-hungry 3.3V add-on boards.

Make sure this fits by entering your model number.
