About the Nearness PCB

Nearness is an open source PCB design by sarnesjo, published on GitHub. It is a 2-layer board measuring 14 × 106.7 mm, with 52 components from 17 distinct parts.

Other key parts include the 926-LME49720MAX/NOPB. By type, the board carries 24 resistors, 16 connectors, 8 capacitors, 2 ICs and 2 diodes.

It belongs with the audio designs in this gallery.

From the project

Minimal panning mixer for the Eurorack modular synthesizer system

Minimal panning mixer for the Eurorack modular synthesizer system. Seven inputs, two outputs. The closer an input is to an output, the greater its influence on it. 3HP.

The pcb directory contains the schematic and PCB layout as a KiCad 5 project.

For convenience, the PCBs are available from OSH Park (front, back).

The panel directory contains a basic panel layout in SVG format, for use with a laser cutter or CNC machine.

Nearness: common questions

How big is the Nearness PCB?

The Nearness measures 14 × 106.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nearness?

52 components, from 17 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 Nearness design files?

From the sarnesjo/nearness repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Nearness design in my own project?

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