Teensy, a USB development board with Arduino support


PJRC Electronic Projects has come out with the $19 Teensy AVR development board. It uses the AT90USB162, which eliminates the need for a separate USB-to-TTL chip:

The Teensy is a complete USB-based microcontoller development system, featuring a 16 MHz AVR (AT90USB162) processor, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard “Mini-B” USB cable and a PC or Macintosh with a USB port.

Key Features:

  • USB can be any type of device
  • 21 I/O pins
  • AVR processor, 16 MHz
  • Single pushbutton programming
  • 15.5K usable Flash memory
  • HalkKay bootloader
  • Free software tools for Mac OS X, Linux & Windows
  • UART, SPI, 4 PWM, 2 timers
  • Tiny size, 1.2 by 0.7 inch
  • Very low cost, only $19

I'm a tinkerer and finally reached the point where I fix more things than I break. When I'm not tinkering, I'm probably editing a book for Maker Media.
