Other key parts include the TL074. By type, the board carries 7 resistors, 3 capacitors, 2 diodes, 1 IC and 1 connector.

It belongs with the audio designs in this gallery.

From the project

Synth DIY stuff

Somewhere to capture and develop some ideas for novel synthesiser modules. Currently that means Eurorack, so +/- 12V power, TS mini jacks, 10V peak-to-peak audio signals.

Not clear at this stage if the end goal is perfboard or PCBs, will see how ambitious the designs get...

Nand: common questions

How big is the Nand PCB?

The Nand measures 35.6 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nand?

14 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nand design files?

From the ajjackson/eurorack repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nand design in my own project?

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