I bought a 32 relays board on ControlEverything: https://shop.controleverything.com/products/32-channel-relay-controller-i2c
It works great but I needed 8 more relays, so I bought https://shop.controleverything.com/collections/relay-controller/products/8-channel-relay-controller-i2c
My particle is on the 32 relays and it’s connected to the 8 relays board with I2C connectors. But how can I set up the address of the 8 relays board ? I don’t understand how address jumpers work.
I’m using the library MCP23008-I2C.h is it ok ?
Thanks for helping
