Other advantages:
- The Arduino Nano module can be replaced easily (Plug & Play).
- Operation at 12V and 24V.
- Opto-isolated digital inputs.
- Use of a standard USB C cable for programming.
- LED indication of the states of the digital inputs and relay outputs.
- Screw terminal blocks for connection to the outside environment.
- I²C expansion port for adding an RTC module or an OLED or alphanumeric display
2x16 characters.
- Protection of the module against supply polarity reversal and overvoltage
(Fuse + Varistor).
