Firmware upgrading 
Use the 6 pin female connector it is clearly marked with UPGRADE or FIRMWARE UPGRADE, note the arrow 
to pin 1 and also the upgrade text is also located closest to pin 1. Actually any USB interface with FTDI232 
chipset can be used - the Arduino boot loader type or our own called TSLRS-USB.  They both fit directly into 
this 6 pin row. 
First install FTDI virtual com port driver

files, in that case you will be notified, about their names, if so, ask support, or google after them.
