TinySound: common questions

What microcontroller does the TinySound use?

The TinySound is built around the STM32G030KxT, from the STM32 family.

How big is the TinySound PCB?

The TinySound measures 15.2 × 15.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TinySound?

23 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the TinySound design files?

From the knurtz/TinySound repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TinySound design in my own project?

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

Can I test firmware for the TinySound 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.
