Review on Flashtree USB Tiny AVR Programmer FabIsp For ATTINY85 Downloader - SEO Optimized by Micheal Looney

I downloaded the USB driver for this programmer board successfully, but my Arduino IDE menu showed the port grayed out. On a whim, I uploaded the blink sketch anyway and it worked without showing a port! I modified the blink rate to be sure it was really writing to the chip and it was. I can't program a UNO without a port number in the IDE, but it doesn't seem to matter in this case. The only disadvantage I've found so far is the serial monitor won't work without an assigned port. If I find problems when I use the Attiny chip in a project, then I may have to come back and lower the rating I gave this board. Update: while the port is not shown in the roll down menu at the top left of the Arduino IDE, the port being used is shown in the lower right of the IDE window. And, while the Attiny does not have the serial port used on the UNO board, a serial monitor can be created for the Attiny in the sketch.
