AVR downloader programmer consists of in-circuit serial programmer (dongle) and small pcb with a DIP socket where you can fit your microcontroller and have it quickly downloader programmed.
Entire AVR downloader programmer has been build with using common parts and fits in the case of the serial connector. The socket pcb has been created to fit a 28-DIP AVR ATmega8 microcontroller, but you can build a socket pcb for any other AVR microcontroller out there. This AVR programmer is compatible with a popular PonyProg software that shows you a status bar of the programming progress.
Make AVR Socket PCB
Supplying microcontroller with external +5V voltage as opposed to taking it directly from computer's serial connection port ensures that the chip is receiving exactly +5V voltage and provides very reliable error free programming. +5V voltage supply for AVR mikrokontroller chip may be provided from external power supply or even better - directly from USB connection.
