Sigmadrive solo: common questions

What microcontroller does the Sigmadrive solo use?

The Sigmadrive solo is built around the STM32F745VETx, from the STM32 family.

How big is the Sigmadrive solo PCB?

The Sigmadrive solo measures 70.7 × 87.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sigmadrive solo?

161 components, from 44 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 solo 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 solo 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 solo 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.
