ZXSwinSID: common questions

What microcontroller does the ZXSwinSID use?

The ZXSwinSID is built around the ATmega88PA-AU, from the AVR/Arduino family.

How big is the ZXSwinSID PCB?

The ZXSwinSID measures 78.4 × 49.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ZXSwinSID?

69 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the ZXSwinSID design files?

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

Can I use the ZXSwinSID design in my own project?

Yes, under the terms of its GPL-3.0 license, which schenkmi chose for the repository.

Can I test firmware for the ZXSwinSID without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
