I just wanted to ask you if I can pair a genuine Arduino UNO v3 with and Ethernet Shield clone (found some on eBay). A friend told me that I might have some issues regarding the main board (fry the board because of the poor quality of the shield), but I don't really think it would be a problem using a clone.
I have 2 ethernet shield clones. Both are from ebay type of place and both are luckily working fine. Yes, some of these shields are poor quality but not all. You do trial and error.
