I just backed the Teensy 3.0 on Kickstarter. It’s designed by Paul Stoffregen, the same wizard behind the Arduino-compatible Teensy boards. It sports a 32-bit ARM Cortex-M4 chip, and is programmable via Arduino and C. This looks like it’s going to be a great platform for building embedded projects that need more power than the typical Arduino. The board is tiny compared to Raspberry Pi.
- 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
At $22, it’s a bargain. The campaign ends on Sept 16, so get them while they’re hot!
