About the Stm32g474-dev board

Stm32g474-dev board is an open source STM32 PCB design by Rennaafi, published on GitHub. It is a 4-layer board measuring 66.7 × 66.2 mm, with 58 components from 36 distinct parts.

Its main chip is the STM32G474RETX, from the STM32 family. Other key parts include the AP2112K-3.3, USBLC6-2SC6 and MCP2562FD-E/SN. By type, the board carries 20 capacitors, 12 connectors, 10 resistors, 4 ICs, 4 diodes and 2 crystals.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

4-layer STM32G474RE dev board (Nucleo-64 headers, USB-C, CAN-FD, STDC14) designed in KiCad 9: schematic, PCB layout, Gerbers & BOM

A 4-layer STM32G474RE (LQFP-64) development board designed in KiCad 9. It follows the NUCLEO-64 header layout (ST morpho CN7/CN10 plus Arduino Uno R3 headers) and adds a native USB-C port, a CAN-FD transceiver, an STDC14 debug connector and four corner mounting holes. There is no on-board ST-LINK; debugging uses an external STLINK-V3 on the STDC14 connector.

Stm32g474-dev board: common questions

What microcontroller does the Stm32g474-dev board use?

The Stm32g474-dev board is built around the STM32G474RETX, from the STM32 family.

How big is the Stm32g474-dev board?

The Stm32g474-dev board measures 66.7 × 66.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Stm32g474-dev board?

58 components, from 36 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 Stm32g474-dev board design files?

From the Rennaafi/stm32g474-dev-board 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 Stm32g474-dev board design in my own project?

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

Can I test firmware for the Stm32g474-dev board 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.
