IBIS to USB Converter

This project is a hardware solution for communicating with miscelaneous IBIS devices (BUSE BS210 etc.)

Features

  • Converts IBIS protocol to USB (virtual COM port)
  • Mini USB
  • Open hardware design (schematics and PCB in KiCad)

Getting Started

  1. Open the schematic and PCB files in KiCad.
  2. Manufacture the PCB and assemble the components as specified.
  3. Connect the IBIS and USB.
  4. Use PuTTY to comunicate (1200 bit/s, 7 bits, even parity, 2 stop bits) or IBIS-Wagenbus Utility

License

This project is open-source. See the LICENSE file for details.

Questions

How big is the IBIS PCB?

It measures 50 × 65 mm and has 2 copper layers, 1.6 mm thick.

What parts does the IBIS use?

25 parts, built around the CH340G, 1N4749A, BC337 and BC547. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the IBIS KiCad files?

From the xtomasnemec/IBIS2USB repository on GitHub, at the commit this page was made from: the board is IBIS.kicad_pcb and its schematic IBIS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the IBIS design in my own project?

Its repository states no licence, so its author keeps all rights: ask xtomasnemec before reusing the design.
