Hi guys, im working with the chip 23017(GPIO Expander).

I have knowledge for this CHIP but i dont want program new library. So i want ask you what is the best node for this CHIP.

I did a quick search but I was not convinced by any node.

I am attentive to your help to recommend me a node.

Note: I'm not working with a raspberry
