Getting Started with the MKR 485 Shield
The MKR 485 shield allows a MKR board to connect to other 485 devices.
This board may be used with the Arduino RS485 and the Arduino Modbus libraries, available from the Library Manager.
Usage notes
The Arduino MKR 485 allows the Arduino MKR family of boards to communicate with industrial automation systems or to extend the serial wired communication over much longer range. This shield supports half and full duplex with or without biasing and termination, master slave configuration. Most of these configurations are physical and the 3 ways dip switch allows you to set up the connection properly.
| Switch No. | ON | OFf |
|---|---|---|
| 1 | Termination on A-B* | NO termination |
| 2 | FULL Duplex* | HALF Duplex |
| 3 | Termination on Y-Z* | NO termination |
(* Factory configuration)
Tutorials
Now that you have a basic knowledge of the shield, you may find inspiration in our Project Hub tutorial platform
