About the VCF carrier board
VCF carrier board is an open source STM32 PCB design by JordanAceto, published on GitHub under the CC-BY-4.0 license. It is a 2-layer board measuring 99.1 × 99.1 mm, with 52 components from 27 distinct parts.
Its main chip is the STM32F405RGT6, from the STM32 family. Other key parts include the AMS1117-3.3, MAX6035xxUR50 and TL072. By type, the board carries 20 resistors, 10 connectors, 10 capacitors and 4 ICs.
It belongs with the dev boards & breakouts and audio designs in this gallery.
From the project
modular analog synthesizer for a.p.
PCB which houses various VCF "plug-in" boards. This pcb contains a 3-input signal mixer and 3-input CV mixer, as well as inputs and outputs for the plug-in board port.
The plug-in boards must conform to the electrical and mechanical interface defined by this pcb.
Plug-in boards must accept a CV range of 0v to +2.048v, and a feedback CV range of 0v to +2.048v.
See the CEM3320 VCF and optical phasor documents for examples of plug-in boards.

VCF carrier board: common questions
What microcontroller does the VCF carrier board use?
The VCF carrier board is built around the STM32F405RGT6, from the STM32 family.
How big is the VCF carrier board?
The VCF carrier board measures 99.1 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the VCF carrier board?
52 components, from 27 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 carrier board design files?
From the JordanAceto/angelo_modular repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the VCF carrier board design in my own project?
Yes, under the terms of its CC-BY-4.0 license, which JordanAceto chose for the repository.
Can I test firmware for the VCF carrier board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
