IO-Warrior Expansion Board

Measurement and control using your (old) PC

IO-Warrior Expansion Board
Don’t throw out your old PCs and notebooks or leave them gathering dust in the basement! They can be a useful resource: by adding this universal interface card an old PC can be pressed into service as a measurement and control hub. An IO-Warrior module on the I/F board takes care of USB communication, and source code is available that works with the free version of Visual Studio.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.

Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.

Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
