About
Many pieces of test & measurement equipment feature a connectivity port labelled "GPIB" which stands for General Purpose Interface Bus. On some equipment this can also be labelled as "HPIB" after the company that originally invented it.
Commercial USB to GPIB adapters contain a lot of features and functionality, but are also very expensive ($500+ new). This is well out of price range for most hobbyists, as well as plenty of engineers and scientists. A lot of people don't need all of the advanced GPIB communication functionality; some are just looking to download multimeter readings or oscilloscope waveforms to their PC. This firmware project aims to implement as much GPIB communication functionality as possible, while still remaining accessable.
Another limitation of your typical USB to GPIB adapter is the development environment restriction due to the required drivers. For example, these vendors only provide Linux drivers for Red Hat-based distributions, but these drivers do not include MATLAB bindings! Instead of having to deal with all sorts of GPIB and VISA driver stuff, this GPIBUSB adapter presents itself to the attached PC as a serial port, allowing a wide variety of operating systems and development environments to utilize it. So although this means that this adapter is NOT a drop in replacement for convential ones, this flexability is desired by many.

Questions
How big is the Usb to gpib PCB?
It measures 55.1 × 54.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb to gpib use?
35 parts, built around the PIC18F4520-I/P, SN75160BN, SN75162BDW and FT230XQ-R. 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 Usb to gpib KiCad files?
From the koson/gpibusb-pcb repository on GitHub, at the commit this page was made from: the board is usb_to_gpib.kicad_pcb and its schematic usb_to_gpib.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb to gpib design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
