USB device to load program into AVR (ATmega, ATtiny ...)

This project's aim it to program AVR devices.

I have used an atMega8 into this design to convert data from USB to ISP protocol.


The firmware of this device is based on source code of similar project: USBtinyISP (


Avrdude recognize this device as an USBtinyISP device (no patch needed for avrdude).


PCB has already been produced for this device, and it works :)

Photo has been taken on version 1.0 of this project (some manual modifications have been done).


Project updated to revision 1.2.
