Overview
Potproto is an open-source printed circuit board by bmoren, from the bmoren/6x-potentiometer-prototype repository on GitHub. It is a 2-layer board of 103 × 21.7 mm with 8 parts on 8 nets, routed with 111 tracks and 0 vias.
README
README.md6x-potentiometer-prototype
6 potentiometers broken out into a stand alone board for prototyping.
REV2 is best produced with OSHPPARK's Aftferdark Service.
Each potentiometer is wired up the following:
- Pin 1: Ground (AGND)
- Pin 2: accessible via pin socket
- Pin 3: + (vcc / 3.3v / 5v)
Each potentiometer's analog signal is accessible via the 1-6 pins corresponding to the potentiometer L->R
GND & voltage inputs available in each pins bank.
See the schematic for more details.
Recommended Potentiometers:
- Alpha vertical 9mm (thonk) (modular addict)
- 9mm Tall trimmers (thonk) (modular addict)
For modular prototyping I suggest using 4x B10K & 2X A10k for linear and logarithmic taper options.
Recomended jumpers:
- Square tipped jumpers (adafruit)
Recomended Pins:
8x 2.54mm Vertical Pin headers for female/female jumper cables 8x 2.54mm Vertical Pin sockets for male/male jumper cables 8x 2.54mm Angled Pin headers to keep the potentiometers as free from cable interference as possible

Questions
How big is the Potproto PCB?
It measures 103 × 21.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Potproto use?
8 parts. 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 Potproto KiCad files?
From the bmoren/6x-potentiometer-prototype repository on GitHub, at the commit this page was made from: the board is potproto.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Potproto design in my own project?
Its repository states no licence, so its author keeps all rights: ask bmoren before reusing the design.
