SDG3: common questions

What microcontroller does the SDG3 use?

The SDG3 is built around the Arduino_Due_Shield, from the AVR/Arduino family.

How big is the SDG3 PCB?

The SDG3 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SDG3?

73 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the SDG3 design files?

From the christopherwj/SDG3 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SDG3 design in my own project?

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

Can I test firmware for the SDG3 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.
