I've ordered this kit to flash other MCUs and to practice SMD soldering. I ordered two boards because they were cheap and I figured when I lose a part I'd have a spare kit to salvage from. I was glad I ordered two because I broke one LED while soldering, error on my part :D I did solder a normal usb plug instead of building up solder for it to connect in a normal port though but that totally works.
This was a great kit to practice SMT soldering. It provided a welcome challenge for an SMT novice such as myself.
The printout shipped with the kit was mostly adequate but was hard to read in some places. It would be nice to carry over the color coding of the components into the diagrams for quick reference. The images here on Tindie helped fill the gaps although I would have liked to see a diagram of the back side components as well (I only visited matrixstorm.com after the fact). I also had to refer to the schematic to find out where to place the second 10k resistor since it wasn't on the printout.
Overall it's a nice piece of kit for $5 and impressive that it can be shipped across the world for a buck. It will provide a great platform for future USB projects.
I really like this kit - it's relatively easy to solder even for SMT beginners (it was my first try at SMT and it turned out great), and the end product is a very nicely looking and versatile atmega8 board.
With the usbasploader bootloader it's very easy to upload new firmware, and with plenty VUSB example code around the web it's easy to write code for it.
I'd say it's impossible to beat the price tag for this kind of kit as well.
The documentation (instructions for soldering the kit) could be improved a bit (which I expect it will in a bit, since the kit is quite new now, and using the stick is quite well documented).
