Gpib4pi: common questions

What microcontroller does the Gpib4pi use?

The Gpib4pi is built around the SSW-120-01-T-D-006, from the Raspberry Pi family.

How big is the Gpib4pi PCB?

The Gpib4pi measures 85 × 56 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Gpib4pi?

43 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Gpib4pi design files?

From the lightside-instruments/gpib4pi repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Gpib4pi design in my own project?

Yes, under the terms of its TAPR-OHL-1.0 license, which lightside-instruments chose for the repository.

Can I test firmware for the Gpib4pi without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
