Teensy USB Development Board
The Teensy is a complete USB-based microcontroller
development system, in a very small footprint, capable
of implementing many types of projects.
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.
Update: New lower price, Teensy is now only $16. :-)
Key Features:
- USB can be any type of device
- AVR processor, 16 MHz
- Single pushbutton programming
- Easy to use Teensy Loader application
- Free software development tools
- Works with Mac OS X, Linux & Windows
- Tiny size, perfect for many projects
- Available with pins for solderless breadboard
- Very low cost & low cost shipping options

Teensy Loader Application
| |
The Teensy Loader makes getting
code into your Teensy easy. Just press and release the reboot
button and the processor runs the HalfKay bootloader, which is automatically
detected. Teensy Loader lets you download your code and reboot to it.
Automatic mode downloads and reboots to your code the instant your computer
detects HalfKay. The latest version of your code is always used. Just
press the button and within 1 to 2 seconds your latest code is running!

Software Development Tools
WinAVR C compiler.
Teensyduino, add-on for Arduino IDE.
Simplified USB Examples or
Dean Camera's LUFA library.
Breadboard Usage
The Teensy is available with header pins,
for direct no-soldering-required
use on a breadboard, which can also be run from the +5 volt from the
USB cable. Standard
Teensy boards come with solder pads. Either way, all Teensy boards come
fully assembled and tested, so no surface mount soldering is needed.
The Teensy with header pins is easy to use with a solderless breadboard

The
128x64 Graphics LCD can be used
with Teensy 2.0 and Teensy++ 2.0 and Teensyduino using this
GLCD library. They fit together nicely on a single
breadboard.
