Teensy 3.0

Teensy 3.0

I’ve been using Teensy-Arduino compatible boards for several years, and this new version looks very promising. It is programmable from inside the arduino IDE. The Teensy 3.0 is a 32bit ARM Cortex-M4 running at 48mhz with some of the following specifications:

  • 32 bit ARM Cortex-M4 48 MHz CPU (M4 = DSP extensions)
  • 128K Flash Memory, 16K RAM, 2K EEPROM
  • 14 High Resolution Analog Inputs (13 bits usable, 16 bit hardware)
  • 34 Digital I/O Pins (10 shared with analog)
  • 10 PWM outputs
  • 8 Timers for intervals/delays, separate from PWM
  • USB with dedicated DMA memory transfers
  • 3 UARTs (serial ports)
  • SPI, I2C, I2S, IR modulator
  • I2S (for high quality audio interface)
  • Real Time Clock (with user-added 32.768 crystal and battery)
  • 4 general purpose DMA channels (separate from USB)
  • Touch Sensor Inputs
  • You can order a Teensy 3.0 from adafruit.com, however the supporting software is in early beta.
