SID MB: common questions

What microcontroller does the SID MB use?

The SID MB is built around the PIC18f4685, from the PIC family.

How big is the SID MB PCB?

The SID MB measures 99.1 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SID MB?

89 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the SID MB design files?

From the Ixox/midibox-SID repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SID MB design in my own project?

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

Can I test firmware for the SID MB without the hardware?

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