The Arduino RS485 is a widely used industrial standard for robust, long-distance communication that is immune to interference. To facilitate this, we have designed a specially crafted RS485 shield for the Arduino controller board. This shield transforms the UART/Serial protocol into the RS485 protocol, thereby providing easy access to the industrial standard for Arduino users.
Features
-
Integrated a standard RS485 port, a mini RS485 port, RS485 headers
-
Provide the welding areas to make full use of the free space. And more importantly, it's convenient for your DIY design.
-
Switch between automatic mode and manual transmission mode, which expands the scope of application.
-
Besides Tx/Rx interface, there is a switch to block/disable this shield, when Arduino needs to be programmed.
-
Gold immersion PCB. Long pins on the back adapt to most Arduino controllers.
