The bus extension for LAN controllers allows splitting 1× RJ-12 into 9 ports for connecting multiple devices. It supports I2C and 1-Wire buses and includes a 6-wire cable for direct connection to LK.
Warning: Do not connect I2C bus cables longer than 3 m or 1-wire buses not originating from tinycontrol with more than 3 wires in the RJ-12 plug. This may cause improper functioning of the I2C bus.
