 ### Star + Pass-Through
-If you have more than one LaserCAN, you can use the Star method to connect the first LaserCAN, and connect the rest through passthrough, starting at the first LaserCAN's unoccupied pads. Ensure you place a 120ohm termination resistor at the last LaserCAN, between the CANH and CANL pins.
