Design with 1-Wire distributor 7 - Star Bus in Cirkit DesignerThe 1-Wire Distributor 7 - Star Bus (Manufacturer Part ID: 11166) by Esera is a specialized component designed to simplify the connection of multiple 1-Wire devices in a star topology. It enables efficient communication and power distribution across multiple devices connected to a single 1-Wire bus. This distributor is ideal for applications requiring reliable and organized 1-Wire networks, such as home automation, industrial monitoring, and sensor networks.
This circuit controls multiple high-torque bus servos using a bus servo adaptor, which is powered by a 6-channel power module. The servos receive their control signals and power through the adaptor, enabling synchronized movement for applications requiring precise and powerful actuation.

This circuit is designed for a bus stop system with GPS tracking and audio announcement capabilities. It uses an Arduino UNO to interface with a Neo 6M GPS Module for location tracking, a DFPlayer MINI for audio playback through a connected loudspeaker, and an LCD screen (16x2 I2C) for displaying location information. The system is powered by a 12V power supply with a DC-DC converter to step down the voltage for the components.

Q: Can I use this distributor with a 3.3V 1-Wire master?
A: Yes, but ensure that all connected devices are compatible with 3.3V operation.
Q: How many devices can I connect to the distributor?
A: You can connect up to six devices, one per port (P1 to P6).
Q: Does the distributor provide ESD protection?
A: No, external ESD protection is recommended for environments prone to electrostatic discharge.
Q: Can I use this distributor in a parasitic power mode?
A: Yes, the distributor supports parasitic power mode, but ensure the power supply can handle the additional load.
