VCA Module: common questions
What microcontroller does the VCA Module use?
The VCA Module is built around the Teensy4.0, from the NXP family.
How big is the VCA Module?
The VCA Module measures 45.7 × 106.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the VCA Module?
50 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the VCA Module design files?
From the Fora888/fully-digital-modular-hardware-synthesizer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the VCA Module design in my own project?
Yes, under the terms of its MIT license, which Fora888 chose for the repository.
Can I test firmware for the VCA Module without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
