Running 4 arduino(clone) boards on one PC - possible???

I have four arduino clones that i need to run on one PC. only 1 works, the other 3 throw up sync errors to do with avrdude (whetever that is)

The error is not with the boards i hope, i sent three back and the replacements throw the same error, so i'm really struggling

Any help Greatly appreciated Toby

We really need a lot more detail than that.

What you can do to test : - move the working 328 to a failing board (swap IC) to detect if the error is in the chip or in the board. - if you preload it with some code you can test the board e.g. blink leds serial ports etc.

avrdude is the utility the IDE uses to program the Arduino.

Are all three boards the same variant?
