If you prefer a i2c board without the need to wire everything yourself you could also use something like this https://www.ebay.co.uk/itm/114237194670?chn=ps&_ul=GB and use my driver for it. The addressing allows for 8 boards, so you can have 64 stations in total.

p.s. There are also boards with a pcf8574 and pcf8574A. like: https://www.ereshop.com/shop/index.php?m...cts_id=789
If you have 8 boards of the 8574 and 8 boards of 8574A then you have a total of 16 boards effectively having 128 stations.
