Stm32g474: common questions

What microcontroller does the Stm32g474 use?

The Stm32g474 is built around the STM32G474QETx, from the STM32 family.

How big is the Stm32g474 PCB?

The Stm32g474 measures 56.8 × 57 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Stm32g474?

100 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Stm32g474 design files?

From the Jayanth-M0625/MRL repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Stm32g474 design in my own project?

The repository has no license, so all rights stay with Jayanth-M0625. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Stm32g474 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.
