Overview
Nearness is an open-source printed circuit board by sarnesjo, from the sarnesjo/nearness repository on GitHub. It is a 2-layer board of 39.4 × 106.7 mm with 52 parts on 32 nets, routed with 148 tracks and 10 vias.
It is built around the LME49720NA and 1N5819HW. Its parts include 24 resistors, 16 connectors, 8 capacitors, 2 ICs and 2 diodes. It belongs with the audio and music boards of this library.
Main components
2README
README.mdNearness
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.
A product of the llllllll community.
PCB
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).
Panel
The panel directory contains a basic panel layout in SVG format, for use with a laser cutter or CNC machine.
Alternative panel designs are available:
Build guide
- Start with the surface-mount components. Mind the orientation of the ICs and diodes.
- Then do the pin headers.
- Then the jacks.

Questions
How big is the Nearness PCB?
It measures 39.4 × 106.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nearness use?
52 parts, built around the LME49720NA and 1N5819HW. 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 Nearness KiCad files?
From the sarnesjo/nearness repository on GitHub, at the commit this page was made from: the board is pcb/nearness.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nearness design in my own project?
Its repository states no licence, so its author keeps all rights: ask sarnesjo before reusing the design.
