From the project

A 4-layer STM32-based compact wireless core board featuring USB Type-C, 50Ω RF microstrip, and dedicated power layers designed in KiCad.

A compact, 4-layer reusable STM32 wireless core board designed in KiCad. It functions both as a standalone USB-to-Wireless dongle/sniffer and as a modular core block for integration into larger IoT and embedded carrier boards.

MCU & Core: STM32 microcontroller with integrated RF capabilities. 4-Layer Optimized Stackup: Layer 1 (Top): High-speed signals, RF trace, and localized GND polygon. Layer 2 (Inner 1): Solid, unbroken Ground Reference Plane for signal integrity and RF return paths. Layer 3 (Inner 2): Dedicated power plane split (3.3V and VBUS) optimized with Non-Functional Pad (NFP)…

STM32-4Layer-Wireless-CoreBoard: common questions

What microcontroller does the STM32-4Layer-Wireless-CoreBoard use?

The STM32-4Layer-Wireless-CoreBoard is built around the STM32WB55CEU6, from the STM32 family.

How big is the STM32-4Layer-Wireless-CoreBoard PCB?

The STM32-4Layer-Wireless-CoreBoard measures 60.6 × 26.5 mm, has 4 copper layers and is 1.58 mm thick.

How many components are on the STM32-4Layer-Wireless-CoreBoard?

43 components, from 26 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 STM32-4Layer-Wireless-CoreBoard design files?

From the gorkemguven/STM32-4Layer-Wireless-CoreBoard 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 STM32-4Layer-Wireless-CoreBoard design in my own project?

Yes, under the terms of its MIT license, which gorkemguven chose for the repository.

Can I test firmware for the STM32-4Layer-Wireless-CoreBoard 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.
