JTAG Adapter for AVRUSB Programmer

JTAG Adapter for AVR USB Programmer

This adapter is supplied with AVRUSB programmers ordered AFTER Jan 2006. This adapter is for older AVRUSB programmers. The latest software, available on support pages, includes JTAG option and can be downloaded.
This adapter lets you use the JTAG programming algorithm with the Kanda AVR USB programmer.
JTAG programming works with newer AVR ATmega microntrollers with 40-pins or more and is much faster than serial programming. With this adapter one AVR USB programmer can do both.

Features
As this is an add-on to the AVR USB programmer, you get the best of both worlds. The existing serial programming still works for AVR microcontrollers without JTAG or boards without the JTAG interface.
But for new boards, especially if the development has used the JTAG interface, you get a seamless transition to production - and much faster programming speeds.
To swap between modes, you just need to connect the adapter to the programmer and choose JTAG in the new software. To swap back, remove the adapter and select AVR USB. Oh, and you may have to unplug and plug-in the programmer.
