Hi there. I have purchased an arduino uno clone from ebay and have been unable to get it to work on my mac. I have tried many different options within the arduino environment but none seem to communicate with it.the board has an Amtel Mega328p-au 1434 chip which is a lot smaller than the one on my official arduino uno. Has anyone had any experience with these boards? I'm wondering if there might be a driver which needs to be installed or something. Thanks.
Check the USB-UART ic which is present in arduino uno clone board.
You have to install drivers for that, then it will work.
Check if it is from CH341 or FTD
If it is from CH341 family then use this link to download drivers for windows, mac and linux
**broken link removed**
and if it is FTD based ic then you can download from FTD website easily
Thanks! I don't suppose anyone could provide a short explanation on the difference between the standard arduino uno mega328p-pu chip and the one i have just got working(mega328p au)? ive had a look around the web but can't seem to find anything which helps me. the standard one is so much larger!
thanks
