EuroSID: common questions
What microcontroller does the EuroSID use?
The EuroSID is built around the STM32F303RBTx, from the STM32 family.
How big is the EuroSID PCB?
The EuroSID measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the EuroSID?
222 components, from 97 distinct parts. The full bill of materials is listed on this page.
Where can I download the EuroSID design files?
From the activexray/EuroSID repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the EuroSID design in my own project?
The repository has no license, so all rights stay with activexray. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the EuroSID 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.
