FAST, AFFORDABLE PROTOTYPINGAND
DEVELOPMENT
The STM32 Open Development Environment (ODE) is an open, flexible, easy and affordable way to
develop innovative devices and applications based on the STM32 32-bit microcontroller family combined
with other state-of-the-art ST components connected via expansion boards. It enables fast prototyping
with leading-edge components that can quickly be transformed into final designs.
The STM32 ODE includes the following five elements:
oSTM32 Nucleo development boards. A comprehensive range of affordable development boards for all
STM32 microcontroller series, with unlimited unified expansion capability, and with integrated
debugger/programmer
oSTM32 Nucleo expansion boards. Boards with additional functionality to add sensing, control,
connectivity, power, audio or other functions as needed. The expansion boards are plugged on top of
the STM32 Nucleo development boards. More complex functionalities can be achieved by stacking
additional expansion boards
oSTM32Cube software. A set of free-of-charge tools and embedded software bricks to enable fast and
easy development on the STM32, including a Hardware Abstraction Layer, middleware and the
STM32CubeMX PC-based configurator and code generator
oSTM32Cube expansion software. Expansion software provided free of charge for use with STM32
Nucleo expansion boards, and compatible with the STM32Cube software framework
oSTM32Cube Function Packs. Set of function examples for some of the most common application
cases built by leveraging the modularity and interoperability of STM32 Nucleo development boards
and expansions, with STM32Cube software and expansions.
The STM32 Open Development Environment is compatible with a wide range of development
environments including STM32CubeIDE, IAR EWARM, Keil MDK-ARM, and GCC/LLVM-based IDEs,
with the possibility to integrate the various components such as STM32CubeMX,
STM32CubeProgrammer or STM32CubeMonitor.

The combination of a broad range of expandable boards based
on leading-edge commercial products and modular software,
from driver to application level, enables fast prototyping of ideas
that can be smoothly transformed into final designs.
To start your design:
•Choose the appropriate STM32 Nucleo development board
(NUCLEO) and expansion (X-NUCLEO) boards (sensors,
connectivity, audio, motor control etc.) for the functionality you need.
•Select your development environment (IAR EWARM, Keil MDK and
GCC/LLVM-based IDEs) and use the free STM32Cube tools and
software such as STM32CubeMX, STM32CubeProgrammer,
STM32CubeMonitor or STM32CubeIDE.
•Download all the necessary software to run the functionality on the
selected STM32 Nucleo expansion boards.
•Compile your design and upload it to the STM32 Nucleo
development board.
•Then start developing and testing your application.
Software developed on the STM32 Open Development
Environment prototyping hardware can be directly used in an
advanced prototyping board or in an end product design using
the same commercial ST components, or components from
the same family as those found on the STM32 Nucleo boards.
