This is an expansion board for UNO R3, and the code(sketch) we provide is only used to test the experimental hardware.
If you need more functionality, write your own code. We do not provide additional code(sketch) and technical support

For more information details, please contact me.

How to use: See video
''DNUNA16_6DI_4Relay_DEMO''
