AVR ISP My New Toy

Here's my new toy...

The Atmel AVR ISP is an In-System Programmer for Atmel’s AVR Flash Microcontrollers. The AVR ISP gives the designer a compact and reliable programming tool to program all In-System Programmable AVR microcontrollers through a 6- or 10-pin ISP connector.

The AVR ISP uses AVR Studio®, Atmel’s Integrated Development Environment (IDE) for code writing and debugging. The programming software can be controlled from both a Windows® environment and a DOS command-line interface. 

The AVR ISP kit includes the following features:

	AVR Studio Interface
	ISP Programming of all In-System Programmable AVR Devices
	Programs both Flash and EEPROM
	Supports Fuse and Lock Bit Programming
	Supports RC Oscillator Calibration
	Upgradeable to Support Future Devices
	Operates at Voltages from 2.7V to 5.5V
	Adjustable Speed. Supports all Target Boards Running at a Speed Higher than 8 kHz
	RS-232 Interface
	Powered from Target. No need for Additional Power Supply

Test mounting FT245BM.

Can't wait for daylight...just installed the FT245BM using fine tip soldering iron..:D

All done! Take some time to review all my soldering and parts placement...

Board after baking..:D

TH components installed.

The looks and the glory of my mighty little USB Programmer.

Time to test this beast if its gonna work...
