Mini-Spectrum-Analyzer-: common questions

What microcontroller does the Mini-Spectrum-Analyzer- use?

The Mini-Spectrum-Analyzer- is built around the STM32G031K8T6, from the STM32 family.

How big is the Mini-Spectrum-Analyzer- PCB?

The Mini-Spectrum-Analyzer- measures 50 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Mini-Spectrum-Analyzer-?

61 components, from 38 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 Mini-Spectrum-Analyzer- design files?

From the Dhruv2212-star/Mini-Spectrum-Analyzer- 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 Mini-Spectrum-Analyzer- design in my own project?

The repository has no license, so all rights stay with Dhruv2212-star. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mini-Spectrum-Analyzer- 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.
