STM32F405rg: common questions

What microcontroller does the STM32F405rg use?

The STM32F405rg is built around the STM32F405RGT6, from the STM32 family.

How big is the STM32F405rg PCB?

The STM32F405rg measures 61.2 × 47.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the STM32F405rg?

50 components, from 35 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 STM32F405rg design files?

From the Arpan12/STM32F405rg 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 STM32F405rg design in my own project?

The repository has no license, so all rights stay with Arpan12. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the STM32F405rg 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.
