Carte stepper: common questions

What microcontroller does the Carte stepper use?

The Carte stepper is built around the STM32G491KEUx, from the STM32 family.

How big is the Carte stepper PCB?

The Carte stepper measures 70 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Carte stepper?

51 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Carte stepper design files?

From the evolutek/carte-actionneurs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Carte stepper design in my own project?

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

Can I test firmware for the Carte stepper 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.
