Sigmadrive duo: common questions

What microcontroller does the Sigmadrive duo use?

The Sigmadrive duo is built around the STM32F745VGTx, from the STM32 family.

How big is the Sigmadrive duo PCB?

The Sigmadrive duo measures 85 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sigmadrive duo?

185 components, from 46 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Sigmadrive duo design files?

From the mstoilov/sigmadrone-esc repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Sigmadrive duo design in my own project?

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

Can I test firmware for the Sigmadrive duo 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.
