2. How do you connect at least 2 IO PI Plus's together?
To connect 2 or more IO Pi Plus boards on a Raspberry Pi you can stack them by plugging the 40-pin header on the boards together. You will need to change the I2C addresses for the chips on each board so that they each have a different address. The I2C Address Selection section on the IO Pi Plus product page details how to change the address solder jumpers to give each IO chip a different address.
If you are stacking several boards on top of a Raspberry Pi I would recommend using our mounting kits to securely mount the boards together.
