STM32 Finder

⚠️We have decided to discontinue the STM32Finder app 30th of April 2026 as our ecosystem evolves. Using an app to find the right MCU is no longer the most effective approach.
For the latest and most comprehensive resources, please visit our Developer Zone (https://www.st.com/content/st_com/en/stm32-mcu-developer-zone.html) for MCUs or Developer Zone for MPUs (https://www.st.com/content/st_com/en/stm32-mpu-developer-zone.html), depending on your needs. You can also explore all our products on the MCU Portfolio page (https://www.st.com/content/st_com/en/stm32-mcu-developer-zone/mcu-portfolio.html) and the MPU Portfolio page (st.com/en/microcontrollers-microprocessors/stm32-arm-cortex-mpus.html#products).
Thank you for your understanding as we continue to improve your development experience.

The STM32 Finder application enables you to explore and connect to the complete portfolio of STM32 Arm® Cortex®-M and Cortex®-A microcontrollers and microprocessors and their associated STM32 development boards.

STM32 Finder features easy-to-use selection tools that provide you direct access to documentation, and a connection to STM32 communities. You will find the microcontroller, microprocessor or development board part number that best fit your application thanks to an easy search with multiple criteria including core type, CPU frequency, memory, price, package, I/Os, temperature grade, and peripherals such as control, timers, analog, connectivity, multimedia and security. From the application, you will also have the possibility to directly buy devices or development boards on-line.

You will have quick access to data and technical resources to support your microcontroller or microprocessor projects, including manuals such as datasheets, reference manuals, application notes, user manuals, programming manuals, or errata sheets.

While you start STM32 Finder on-line, the application and portfolio database are updated automatically and optimally, but everything will remain fully functional while you are off-line.

The application adapts automatically to the screen size and orientation.

STM32 Finder will also help you to connect with the developer communities on popular social platforms such as Facebook™, YouTube™ channel, and ST Wiki and Community.
