About the STM32-RF PCB

STM32-RF is an open source STM32 PCB design by AmziSys, published on GitHub. It is a 4-layer board measuring 39 × 15 mm, with 38 components from 29 distinct parts.

Its main chip is the STM32L432KBU6, from the STM32 family. Other key parts include the XC6206P332MR, USBLC6-2SC6 and nRF24L01P. By type, the board carries 18 capacitors, 5 resistors, 4 ICs, 4 inductors, 3 connectors and 2 diodes.

It belongs with the rf & radio designs in this gallery.

From the project

The board contains an STM32 microcontroller, an RF transceiver and antenna interface as well as a USB full-speed interface

* Intro: The idea of the board is to be used in a system where data is sent over the air. The data is received by the antenna and processed in the microcontroller then sent out to a host computer via the USB interface.

* Design: The board contains: - STM32L432KBU6: STM32 microcontroller - nRF24L01P: 2.4GHz RF transceiver suitable for ultra-low power wireless applications (ISM band) - Power supply: USB, ESD protection, Fuse, and LDO regulator - Antenna interface and its matching circuit - R and C

STM32-RF: common questions

What microcontroller does the STM32-RF use?

The STM32-RF is built around the STM32L432KBU6, from the STM32 family.

How big is the STM32-RF PCB?

The STM32-RF measures 39 × 15 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the STM32-RF?

38 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the STM32-RF design files?

From the AmziSys/STM32-RF repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the STM32-RF design in my own project?

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

Can I test firmware for the STM32-RF 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.
