Audio-DSP-Guitar-Pedal: common questions
What microcontroller does the Audio-DSP-Guitar-Pedal use?
The Audio-DSP-Guitar-Pedal is built around the STM32F446RETx, from the STM32 family.
How big is the Audio-DSP-Guitar-Pedal PCB?
The Audio-DSP-Guitar-Pedal measures 136 × 186 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Audio-DSP-Guitar-Pedal?
260 components, from 60 distinct parts. The full bill of materials is listed on this page.
Where can I download the Audio-DSP-Guitar-Pedal design files?
From the Jonkaphi/Audio-DSP-Guitar-Pedal repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Audio-DSP-Guitar-Pedal design in my own project?
The repository has no license, so all rights stay with Jonkaphi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Audio-DSP-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.
