I got into AVR chips because they are easy to program, and that has become more and more true over the years with the ever-falling cost of programmers. But it’s pretty easy to make a mistake when burning the fuses on the chips and if you don’t have a proper programmer (my first programmer was a horrifyingly slow self-built DAPA cable) you’ll have a brick on your hands. This little board may be able to help in that situation. I gave the USB µISP a try this week. The half-stick-of-gum-sized board flashes firmware like a champ and includes a rescue pin for when you have clock source problems.
My full review is below. All technical information for the µISP can be found in the User’s guide. The board itself is now available to purchase in the Hackaday Store.
