About the UsbGpib PCB

UsbGpib is an open source AVR/Arduino PCB design by xyphro, published on GitHub under the MIT license. It is a 2-layer board measuring 54 × 15 mm, with 21 components from 14 distinct parts.

Its main chip is the ATMEGA32U4-MU, from the AVR/Arduino family. By type, the board carries 8 resistors, 7 capacitors, 2 diodes, 1 IC, 1 crystal and 1 connector.

It belongs with the usb & debug tools designs in this gallery.

From the project

Versatile, cheap and portable USB to GPIB converter (USBTMC class based)

The new HW revision picks up some things that I and other misliked: - The REV 1 HW - when put beeing assembled into its housing did have change to colide with parts of the instruments body. Especially for Keysight equipment. This new HW revision follows the formfactor of an original GPIB cable to get rid of this mechanical constraint. - The REV 1 HW required to enter the bootloader with a tweezer. REV 2 has a button. Hold it a few seconds and the bootloader is entered.

UsbGpib: common questions

What microcontroller does the UsbGpib use?

The UsbGpib is built around the ATMEGA32U4-MU, from the AVR/Arduino family.

How big is the UsbGpib PCB?

The UsbGpib measures 54 × 15 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UsbGpib?

21 components, from 14 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 UsbGpib design files?

From the xyphro/UsbGpib 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 UsbGpib design in my own project?

Yes, under the terms of its MIT license, which xyphro chose for the repository.

Can I test firmware for the UsbGpib without the hardware?

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