## Description

The Teensy 3.2 is about to become your favourite microcontroller board. And here's why:

Created by Paul Stoffregen and the team from PJRC, the Teensy 3.2 is a microcontroller development board running a 32-bit ARM Cortex M4 processor, clocking in at 72MHz (overclockable to 96MHz). It also packs 1MB of flash, 4K of EEPROM, and 34 I/O pins. As with the rest of the Teensy platform, what really stands them apart is that they can be programmed using the Arduino IDE and all of the maker-friendly functions that we know and love. You just install the Teensy loader application which runs in the background, and it shows up like a regular Arduino board.

Along with that, Paul has written dozens of great libraries to support the Teensy's advanced hardware functionality which enables projects above and beyond the capacity of standard Arduino board.

## Tech Specs:

- 32 bit ARM Cortex-M4 72 MHz CPU (M4 = DSP extensions)

- 34 Digital I/O Pins (5V tolerance on Digital Inputs)
- 12 PWM outputs
- 7 Timers for intervals/delays, separate from PWM
- USB with dedicated DMA memory transfers
- 3 UARTs (serial ports)
- SPI, I2C, I2S,CAN Bus, IR modulator
- I2S (for high quality audio interface)
- Real Time Clock (with user-added 32.768 crystal and battery)
