The Teensy 3.0 is an Arduino compatible microcontroller developed by Paul Stoffregen, and used by the Tilty Duo, Quad, and Omni. It uses a powerful 32-bit ARM Cortex M4 microcontroller to pack an amazing amount of power and function into a "teensy" package.
- 128K Flash Memory, 16K RAM, 2K EEPROM
- 48 MHz clock speed (overclockable to 96 MHz)
- 34 Digital I/O Pins (all with interrupt capability, 10 surface mount on the bottom of the board, and all 5v tolerant)
- 14 13-bit Analog pins (10 shared with digital I/O pins, 4 surface mount on bottom of the board)
- 10 PWM Channels
- SPI, I2C, and 3 Hardware Serial Ports
- 7 Timers for intervals/delays separate from PWM
There are three variants available as well:
- The "No Headers" variant includes just the Teensy 3.0, without any headers.
- The "With Headers" variant includes headers for the Teensy to plug into a breadboard or a Tilty Duo or Quad. You can choose either standard headers or the special "low-profile" headers required to shorten the Teensy enough to allow add-on board stacking. However, the headers are not soldered to the Teensy.
- The "With Headers Assembled" variant is the same as "With Headers", except that the Teensy will come with the headers pre-soldered and ready to be plugged into a breadboard or Tilty control board.
