The 1 Wire Pi Plus is a communication board supporting the 1-Wire® protocol designed for use on the Raspberry Pi. A 5V buffered I2C port is also provided on the board.
The 1-Wire® port on the 1 Wire Pi Plus is based around a DS2482-100 I2C to 1-Wire® bridge device. The DS2482-100 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 1 Wire Pi Plus and Raspberry Pi from electrostatic spikes on the 1-Wire® port. Connections to the 1-Wire® port can be made through the RJ-12 socket or the solder points on the PCB. We have a knowledge base article for configuring and using the 1-Wire® port on your Raspberry Pi.
The 1 Wire Pi Plus is powered through the host Raspberry Pi using the GPIO port and extended pins on the GPIO connector allow you to stack the 1 Wire Pi Plus along with other expansion boards.
Space is provided on the board for a 1-Wire® iButton device. iButtons are small metal packed modules that can be used for a wide range of functions from data loggers to temperature monitoring. More information about iButtons can be found on the Maxim Integrated website. To use an iButton on the 1 Wire Pi Plus you will need to solder a DS9094F PCB clip onto the board. Please note that the DS9094F should be positioned to match the orientation marked on the PCB and the + sign on the connector is actually linked to the ground side of the iButton devices.
A 5V input port is also provided allowing you to use an external power supply on the 1-Wire® interface, reducing the load on the Raspberry Pi. If you choose to use the external 5V input please remove the jumper on the board to isolate the Raspberry Pi 5V bus.
