Introduction: Arduino RS485 Din Rail Mount

This small instructable will show you how to mount an Arduino together with a RS485 shield in a cabinet on a din rail. You will get a nice and compact device to realise MODBUS slaves, DMX devices, door access units etc.

This instructable will also work, if you want to mount motor or sensor shields together with an Arduino in a cabinet.

Step 1: Tools & Materials



  • soldering iron
  • screw driver
  • side cutting pliers

  • jointing clamp for wire end sleeves (optional)

Step 2: Prepare the Wires

It's recommend to place on one end of the wire a wire end sleeve. If you don't have such wire end sleeves it's also ok to tinning the ends only

Step 3: Soldering the Wires

Now you can solder the wires to the free soldering pads beside the terminals. The wires are connected now with the terminal.

Step 4: Preparing the Shield

The shield will overlap the Arduino. It's recommend to cut the pins of the shield terminal pins close as possible with a side cutting pliers.

Step 5: Connect the Terminal of the Shield

You can connect now the free end of the wires with the removable terminal of the shield.

Step 6: Shield and Arduino Assembly

Please plug all components together as in the picture above.

Step 7: Mount the Top Shell

You can close the device by mounting the top shell
