VCF: common questions
What microcontroller does the VCF use?
The VCF is built around the ATTINY45, from the AVR/Arduino family.
How big is the VCF PCB?
The VCF measures 28 × 110 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the VCF?
72 components, from 56 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 VCF design files?
From the odeliy/noise-reap repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the VCF design in my own project?
The repository has no license, so all rights stay with odeliy. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the VCF without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
