The 1-Wire port is based around a DS2482-800 &DS2482-100 I2C to 1-Wire bridge device.
The DS2482-800 provides bi-directional protocol conversion between the I2C port on the Raspberry Pi and
any attached 1-Wire® slave devices. An ESD Protection Diode is used to
protect the Board and Raspberry Pi from electrostatic spikes on the 1-Wire port.
Connections to the 1-Wire port can be made through pin on the PCB.
