Silent symphony: common questions

What microcontroller does the Silent symphony use?

The Silent symphony is built around the STM32H743VIT6, from the STM32 family.

How many components are on the Silent symphony?

48 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Silent symphony design files?

From the jayis1/hacker-devices repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Silent symphony design in my own project?

The repository has no license, so all rights stay with jayis1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Silent symphony 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.
