best board with 8 inputs

[ndev]

Hi,

I looked into your website and I like all your board.
Great !

You have so many board, it is difficult to find the correct one.
I have a project for which I need at least 4 boards with 8 inputs and some relays (no more than 6 for each).
I will use esphome with Ethernet.


What could be the best board for me ?
KC868-A8
KC868-A8S
KC868-A8S V2
....

Thanks,
