The DCCF is a second edition of the DCCV. It’s a controller board for extending your Eurorack modular synthesizer with DC CV, now six channels on 60mm long-throw fader. +/- 3V outputs by default, switchable to unipolar 0/3V for extra precision, (1.3 volts per inch).
Turn your nanoRings into a real instrument with six channels of control voltage on big faders.
Powered by USB (cable included, charger not) it draws about 75 mA when the LEDS are at maximum. Bipolar leds indicate the polarity and setting output of the six mono TS jacks.
Hand-held at 20x10x1.5 centimeters. It’s portable for performing with friends, you can route long patch cables into your rack and hand off a playing surface to a partner.
Available as a PCB, parts kit, or fully assembled.

I recommend the parts kit over the bare PCB, because you need just the right faders, and the internal power supply and USB socket are particular footprints. Should be explained in the build guide, but do reach out with any questions.
Soldering the USB header is tricky. We’re only using the two outer pins of the five small pins in a micro-USB, they’re ground and power. The data lines are floating unconnected. You’ll want to solder the through-hole pins as structural integrity, because the power cable applies some force on insertion. The micro-USB header also likes to take up excess solder and stuff up the insides, so maybe leave a cable inserted while you work, and be careful not to get excess solder inside the jack. Do this part first so you have room to work: I damaged a fader once reworking it. Test that the power header is installed securely and has voltage going to the regulator before continuing with other parts.
3D Printed Frames. Should be included with your PCBs, but if you need another one, here’s the digital schematics. Two STL files for download. The Ring is the infrastructure binding both layers, the fader base helps elevate the faders, you’ll want six.
