GalernaDsp: common questions
What microcontroller does the GalernaDsp use?
The GalernaDsp is built around the STM32F405RGTX, from the STM32 family.
How big is the GalernaDsp PCB?
The GalernaDsp measures 121 × 121 mm, has 4 copper layers and is 1.726 mm thick.
How many components are on the GalernaDsp?
125 components, from 51 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 GalernaDsp design files?
From the mirrorganger/GalernaDsp 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 GalernaDsp design in my own project?
The repository has no license, so all rights stay with mirrorganger. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the GalernaDsp 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.
