I haven't had any good karma with the Uno R3, only bad juju. On the Arduino web-forum, there are several threads stating that they've found or made drivers work. Looking in Arduino driver folder of the most up-to-date IDE installation, there are only FTDI drivers for Win32 and Win64, nothing to support the Mega16U2. I even installed Arduino's latest version of the IDE with the same results.
I'm being warned that the driver didn't install because Windows could not find a valid descriptor. But I have spent several sessions, including most of today, attempting to find drivers for it or a work-around. With the Duemilanove's and the Mega 1280s the FTDI's work flawlessly. My Toshiba notebook is running Windows 8. I've got two Arduino Duemilanove's with FTDI handling the USB, three Arduino Mega's sporting the AT1280 with FTDI handling the USB and two Arduino Uno R3s with the Mega16U2AT handling the USB. I would like to support the Chinese economy. If your boards are working to your satisfaction, I might just risk droping $30.00 or $40.00 and stock up, the next time I see a deal like that.ĭavid.prentice wrote: AFIK, the UNO R3 clones have a genuine mega16U2. I was leery of getting some because, well, you know.
I'm thinking, how in the heck can they sell the entire, fully populated board, for what only the controller costs. I seen somewhere recently, knock-off boards with this footprint, fully stuffed, for less than $1.00 US. Hey, are these knock-off boards you are describing similar to the Hack-A-Day boards (though, these are priced rather high, I think) that are about 0.6" x 1.6" footprint? So it's very attractive to buy these knock-offs. Assumption is the mother of all f****ups.Ībout these very cheap boards: I cannot even buy a single ATmega328P chip for what I paid. I didn't expect the cable to be the culprit.
