Guitar pedal: common questions

What microcontroller does the Guitar pedal use?

The Guitar pedal is built around the STM32F401RBT6TR, from the STM32 family.

How big is the Guitar pedal PCB?

The Guitar pedal measures 110 × 96 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Guitar pedal?

127 components, from 37 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 Guitar pedal design files?

From the herculanodavi/guitar-pedal 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 Guitar pedal design in my own project?

Yes, under the terms of its MIT license, which herculanodavi chose for the repository.

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.
