The

USBtinyISP

is a simple open-source USB AVR programmer and SPI interface designed by Adafruit Industries. It is low cost, easy to make, works great with avrdude, has both 6 and 10 pin standard ISP cables, is AVRStudio-compatible and tested under Windows and MacOS X.

Using this programmer and avrdude you can program any in-circuit "serial" programmable chip that avrdude supports (which is nearly all of them). It does not do JTAG or High Voltage programming. You can re-program Arduino's (and 'minimal arduinos') using this programmer directly from Arduino's programming environment.

The project is based off of the USBtiny code & design.

Kit includes all parts necessary, including microcontroller, PCB, and enclosure. A standard USB cable (A to B type) is not included, but we're sure you're having some of those around.
