I was unlucky to retrieve 5 Nano boards from a bad quality batch.
When uploading a sketch I am getting an error "avrdude: stk500_getsync(): not in sync" under Arduino IDE on Linux. After hours of debugging I found out that these boards contain the older CH340B chip instead of a CH340G chip found on previously ordered Nano boards from Banggood. See the attached picture.
I did find a workaround for Linux though:
* Download CH341SER_LINUX.ZIP from http://www.wch.cn/download/CH341SER_LINUX_ZIP.html
* unzip ~/Downloads/CH341SER_LINUX.ZIP
* cd CH341SER_LINUX
* make
* sudo make load
* unplug Nano board
* rmmod ch341
* echo blacklist ch341 | sudo tee /etc/modprobe.d/blacklist-ch341.conf
* plug arduino
* make sure ch34x driver is used instead of ch341 driver by running dmesg
* start Arduino IDE
* select " Arduino Duemilanove or Diecimila board" instead of "Arduino Nano"
* upload sketch
This all makes this board very developer unfriendly.
I am regretting this purchase.
