Faderbay: common questions

What microcontroller does the Faderbay use?

The Faderbay is built around the STM32F405RGTX, from the STM32 family.

How big is the Faderbay PCB?

The Faderbay measures 360 × 140 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Faderbay?

174 components, from 48 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 Faderbay design files?

From the vonmartins/faderbay 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 Faderbay design in my own project?

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

Can I test firmware for the Faderbay 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.
