Introduction to the STM32 Open Development Environment

The STM32 Open Development Environment (ODE) is a set of stackable boards and a modular open software environment designed around the STM32 microcontroller family. It enables fast and affordable prototyping and development.

Key Components:

• STM32Cube development software
• STM32 Nucleo expansion boards
• STM32 Nucleo development boards
• STM32Cube expansion software

Building Block Approach: ODE categorizes functionalities into blocks:

• Sense: Accelerometer, gyroscope, inertial modules, magnetometer, pressure, temperature, humidity, proximity, microphone.
• Connect: Bluetooth LE, Sub-GHz radio, NFC, Wi-Fi, GNSS.
• Translate: Audio amplifier, touch controller, operation amplifier.
• Move/Actuate: Stepper motor driver, DC & BLDC motor driver, industrial input/output.
• Power: Energy management & battery.
• Process: General-purpose microcontrollers, secure microcontrollers.
• Software: Software components.

ODE is compatible with multiple Development Environments, including IDEs like IAR EWARM, Keil MDK, and GCC-based environments.

STM32 Nucleo Development Boards (NUCLEO)

Affordable development boards for all STM32 microcontroller series, featuring unified expansion capabilities and integrated debugger/programmer functionality.

Features:

• USB or external power supply.
• Integrated ST-LINK debugger/programmer.
• Support for various STM32 microcontroller families (F0, F1, F2, F3, F4, F7, L0, L1).
• ST morpho extension header.
• Arduino™ UNO R3 extension headers.

STM32 Nucleo Expansion Boards (X-NUCLEO)

Boards adding functionality, designed to plug directly onto STM32 Nucleo boards or stack on other expansion boards.

Categories:

• Sense ?
• Connect ?
• Power ?
• Move/Actuate ⚙️
• Interact ?

An example board (X-NUCLEO-IKS01A1) supports DIL24 for new devices and connects to Motion MEMS and Environmental sensors.
