Prototype stage. First Hub 4, LC1 Bus and Audio USB units are being built, November 2026. Not yet for sale.
CycTronics

Sensor and control modules on one USB cable.

Plug a CycIO Hub 4 into a PC and attach up to four modules: load cells, relays and more. Each module keeps its own serial number and calibration, and every one is driven from the same software interface.

CycIO modules are not safety controllers.

How the system fits together

  1. 01

    The hub talks to the host

    One USB-C cable to a PC or Raspberry Pi. The hub finds the attached modules and routes their messages.

  2. 02

    Each module gets its own port

    Ports are point-to-point, not a shared bus. A short or a crashed module on one port does not affect the others.

  3. 03

    Power is switched per port

    The hub limits current on each port, reports faults and can power-cycle a single module from software.

  4. 04

    Modules keep their identity

    Serial number and calibration are stored on the module. Move it to another port or another hub and your code still finds it.

Software

A few lines of Python read a scale or switch a relay. The same code works whether the module sits on a hub or on its own USB cable.

Progress

What has actually happened so far, newest first.

  1. Snap-fit enclosures designed for Hub 4, LC1 Bus and Audio USB.

  2. Hub 4 and LC1 Bus prototype units sent for assembly, for load-cell scale tests.

  3. First Audio USB prototypes assembled. One issue found and fixed for the second revision.

  4. Hub 4, LC1 Bus, LC4 Bus and Relay4 Bus designs completed.

  5. Hub-and-module architecture chosen: one hub, a dedicated port per module, USB-C cables.

  6. Hardware design started.

Next: bring-up and testing of the first Hub 4 and LC1 Bus units, then Relay4 Bus.
