Title: Arduino nano Chines clone
Post by: PA3040 on Apr 20, 2018, 06:19 pm
Hi

I am using Arduino nano Chines clone and it is  working but only issue is whine external power is connected ( Vin) can't program ( upload ). Once the External power is removed I need to remove the USB cable  and re connect then I can upload without fail.

Please advice and modification to be done or reason to this issue

Thanks in advance

Talk to your chinese clone supplier - this is not an Arduino issue.
