Quick Overview

This new version uses an SMD 5x2 header. This is a simple to use USB AVR programmer. It is low cost, easy to use, works great with AVRDude, and is tested extensively on a Windows desktop. Based on Dick Steefland's USBtiny and Limor Fried's USBtinyISP.

We use this programmer extensively on a Windows box and love it. This programmer works really well for nearly all AVR micros supported by AVRDUDE. This board is buffered and power protected so that you can do some really evil things to the programmer without killing it. It is fast! Comparable speed to the AVR ISP2 USB programmer from Digikey. One of the greatest features of this board is the ability to power the target (up to 500mA) from the programmer.

To use this programmer, attach to a Windows machine and install the drivers listed above. Open a command prompt. Assuming WinAVR (and therefore AVRDUDE) have been installed, type: avrdude -c usbtiny -B 1 -patmega328 -U flash:w:main.hex Be sure to include the "-B 1" flag as this will significantly increase the programming speed! You may need to change -p flag to your appropriate microcontroller.

You can setup a tool and hotkey in Programmers Notepad to do this automatically.
