Guitar Pedal: common questions

What microcontroller does the Guitar Pedal use?

The Guitar Pedal is built around the STM32F446ZCTx, from the STM32 family.

How big is the Guitar Pedal PCB?

The Guitar Pedal measures 169 × 103.5 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Guitar Pedal?

109 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Guitar Pedal design files?

From the lucacros/GuitarePedal_2324Project repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Guitar Pedal design in my own project?

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

Can I test firmware for the Guitar Pedal 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.
