About the Pcbdesign PCB

Pcbdesign is an open source STM32 PCB design by enishyseni, published on GitHub. It is a 4-layer board measuring 55 × 40 mm, with 22 components from 13 distinct parts.

Its main chip is the STM32F405RGT6, from the STM32 family. Other key parts include the AP2112K-3.3TRG1. By type, the board carries 12 capacitors, 4 resistors, 2 ICs, 2 switches, 1 crystal and 1 connector.

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

- VBUS5V: USB-C VBUS → LDO VIN, LDO EN (always-on) - +3V3: LDO VOUT → All MCU VDD pins, VDDA, VBAT, decoupling caps - GND**: All ground pins interconnected

- USBDP (D+): USB-C pin A6 ↔ MCU PA12 (OTGFSDP) - USBDM (D-): USB-C pin A7 ↔ MCU PA11 (OTGFSDM) - CC1: USB-C pin A5 → 5.1kΩ → GND (identifies as UFP/device) - CC2: USB-C pin B5 → 5.1kΩ → GND

Pcbdesign: common questions

What microcontroller does the Pcbdesign use?

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

How big is the Pcbdesign PCB?

The Pcbdesign measures 55 × 40 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pcbdesign?

22 components, from 13 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 Pcbdesign design files?

From the enishyseni/pcbdesign 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 Pcbdesign design in my own project?

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

Can I test firmware for the Pcbdesign 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.
