More Aux Ports on Cube

Hi Guys

How are you?
I have a Cube Black and it has 14 ports (8 PWMs + 6 Aux/GPIOs), however I need more (around 17)

Is there any expander or any GPIO to I2C module converter?

Any ideas/recommendations?

Thanks in advance,

Why do you need that much of output? Depends on the usage, you may try to add some multiplexer, arduino, or even companion computer.
