Please add some text to the PNG file on RS485 requiring a common GND (or galvanic isolation). Otherwise users will blow transceiver on XY-017 module! Unfortunately there is not much information on the net, how to do this properly. Also on most XY-017 the 120 Ohm termination requires a solder bridge...
