My question is pretty much what is shown in the title. I'm using a M-DUINO RS485 half-duplex module as a master in a Modbus network, the typical 120Ohm termination resistor is required at the master side so I was wondering if I needed to add it between A,B or maybe it is already implemented inside the M-DUINO?

Hello Pablo,
The resistance is already implemented inside the M-Duino. To get more information about M-Duino models just have a look here.
Thank you
