About the Kompari PCB

Kompari is an open source PCB design by rhinocerose, published on GitHub. It is a 2-layer board measuring 28.5 × 100 mm, with 34 components from 12 distinct parts.

Other key parts include the TL074. By type, the board carries 15 resistors, 7 connectors, 4 capacitors, 3 LEDs, 3 diodes and 1 IC.

It belongs with the audio designs in this gallery.

From the project

*** ### Features: - 2 ±12V inputs, each with attenuverter - Unipolar/Bipolar output switch - 1 ±10V output, with attenuverter

*** ### Features: - 2 ±12V inputs, each with attenuverter - Unipolar/Bipolar output switch - 1 ±10V output, with attenuverter

Plug any CV or audio source into one of the two inputs, and it will be compared against the other.

The output will be high (+10V) if input A is greater than input B.

The output will be low (-10V if set to bipolar, 0V if set to unipolar) if input B is greater than input A.

Kompari: common questions

How big is the Kompari PCB?

The Kompari measures 28.5 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kompari?

34 components, from 12 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 Kompari design files?

From the rhinocerose/eurorack-designs 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 Kompari design in my own project?

The repository has no license, so all rights stay with rhinocerose. Use it as a reference, and ask the author before reusing the design.
