how do i use the 1 to 3 hub



  • how do i use the 1 to 3 hub? when i connect 3 units (angle, ext and op-180˚) i get an error message saying: Please change unit to other grove port. do i need to use the custom ports?



  • the 1to3 hub is for connecting 3 i2c devices to port A when they have different address.
    For those portB devices you need a PortB HUB
