1 Wire Pi Plus HAT
Description
- 1 Wire Pi Plus HAT
- Features an interface with ESD protection diode
- Is stackable with other Raspberry Pi accessory boards
- Offers a buffered 5V I2C port for 1-Wire interface
- Provides I2C address selection via solder jumpers
The 1 Wire Pi Plus HAT from AB Electronics UK 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 Pi Plus can be securely fitted to your Raspberry Pi using our mounting kit pack.
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.
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.
