AVR Programming Hardware - Serial Port Programmer

This is the schematic of a Serial Port Programmer for the popular programmer software PonyProg and avrdude.

Features:
• Connects to PC via RS232 port (note: It will not work with USB to RS232 converters!)
• No need for external power supply as it takes the power supply from target board.
• It uses Atmel's 2x5 pin ICSP connector layout
