Title: Add power to an Atmel AVRISP MKII
Post by: krupski on Oct 03, 2012, 07:45 pm
Hi all,

I just got an AVRISP MKII and found it didn't supply power to the target device. So I hacked mine.

I found lots of WAY too complicated and convoluted methods on the web... my hack only uses one part - a 1N4001 diode.

The diode needs to be bent into the proper shape to clear the board and to clear the ISP connector - other than that just solder it in and done!

Check the photos for more info (click on a photo for high res):

Be sure the diode points the right direction! LOL
