Got this from ebay. Fail to upload any sketches to it. Ebay seller insisted that he tested the unit before sending it to me. I've selected the correct COM port and board type but still it doesn't work. I have a feeling it's a hardware issue. Please help me. Thanks.
@Legwinskij thanks for your reply. Tried that but doesnt work :( Also, it seems that pressing the reset button has no effect at all.
