Hi nick.

You really only need two of the Quad Realys daisy-chained together with Qwiic cables but you will need to change the I2C address on one of them to something other than the default address. There’s a jumper on the board that lets you do that, just close the jumper on one board.

After you’ve done that, you talk to the first 4 relays on one address and the second 4 relays on the other.
