Stm32-3d printer controller: common questions

What microcontroller does the Stm32-3d printer controller use?

The Stm32-3d printer controller is built around the NUCLE_F446RE_MORPHO_CN7, from the STM32 family.

How big is the Stm32-3d printer controller PCB?

The Stm32-3d printer controller measures 70 × 101.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32-3d printer controller?

78 components, from 25 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 Stm32-3d printer controller design files?

From the j-silv/stm32-3d-printer-controller repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Stm32-3d printer controller design in my own project?

Yes, under the terms of its MIT license, which j-silv chose for the repository.

Can I test firmware for the Stm32-3d printer controller 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.
