1-Wire Automation System

The 1-Wire Automation System consists of a 1-wire host controller board and a single board computer or USB to I2C adapter in a single attractive enclosure. The 1-Wire host controller board contains all the necessary power supplies for powering 1-Wire devices and the single board computer.


  • Integrated Raspberry Pi model 3 with SD card.
  • SD card is pre-installed with latest Raspbian operating system, 1-Wire Automation Software, owfs.
  • 4 independent 1-wire channels based on DS2482-100+ host controllers.
  • ESD protection with DS9503 TVS diodes and polyfuses.
  • Power requirements 24V DC @ 1.5A max.
  • 5V 2A power supply for single board computers via USB connector or screw terminals.
  • 5V 1A power supply for powering 1-wire devices (separate from SBC power supply).
  • 8-20V 1A adjustable auxiliary power supply for powering 1-wire devices.
  • 1-wire power supplies are ESD protected with TVS diodes and polyfuses.
  • 5V and 8-20V power supplies along with 3 extra ground connections can be routed to the 1-wire RJ45 connectors using jumpers. By default, only 1-wire ground and DQ are connected (no jumpers installed).
  • Separate power connector with screw terminals (detachable).
  • 8 GPIO lines on a 10 pin IDC connector for signaling/turning off the single board computer.
  • Extension connector for additional I2C devices.
  • Connector and mounting holes for expansion boards.
  • Galvanically isolated I2C inputs which can operate at 3.3V and 5V signal levels.
  • White acrylic laser cut enclosure.
  • Mounting holes for vertical wall mounting.
