ST's tools for evaluation of the STM32, range from highly affordable community enabled tools up to fully equipped boards, ready for evaluation of every single feature of the selected MCU. All ST evaluation boards include an ST-LINK/V2 in-circuit debugger/programmer.

STM32 Nucleo boards follow a lean approach and are ideal for prototyping and community usage. An Arduino™connector and the ST Morpho connector make an extension with application related add-on hardware easy. All I/Os of the MCU are easily accessible, the boards come with a HAL library and work with IAR, Keil, CCC based IDEs as well as the mbed™ online IDE.

STM32 Discovery kits are a cheap and complete approach for evaluation of the outstanding capabilities of STM32 MCUs. They carry the necessary components, like MEMS microphones, sensors, LCD displays) for demonstration of specific device features. Evaluation and prototyping are facilitated by a HAL library and software examples, IAR, Keil and CCC based IDEs are supported.

STM32 Eval boards, the high end evaluation platform, carry all the required external hardware necessary for using the complete features set of an STM32 Microcontroller. STM32 Eval boards give access to all the pins of the contained microcontroller, even for bigger packages. The HAL library and ready-to-use software examples make application design very easy.

This comprehensive portfolio of evaluation boards is complemented by a wide choice of STM32 evaluation boards developed by ST’s partners.

STM32 Power Shield : EEMBC-approved power-monitoring technology for energy-critical embedded development

To check the power consumption of embedded designs accurately, the STM32 Power shield (X-NUCLEO-LPM01A) provides developers an affordable tool with an ideal measurement range for ultra-low-power devices, such as Internet-of-Things (IoT) endpoints.

The STM32 Power shield features voltage supply to the target from 3.3V down to 1.8V, dynamically monitors the current under various operating conditions from 100nA to 50mA, measures static current from 1nA to 200mA, and also performs direct EEMBC benchmark measurements with a fast acquisition rate of 3.2 Msample/s. The STM32 Power shield has indeed been selected by EEMBC as the reference platform (Energy Monitor v2.0) for the IoTConnect and ULPMark benchmarks.

Firstly, with its built-in display, the STM32 Power shield can be used autonomously without the need of any external equipment. Secondly, its companion graphical PC application STM32CubeMonitor-Power (STM32CUBEMON-PWR) aims at setting parameters of the STM32 Power shield and visualizing the data captured to help developers meet their budget of power consumption. STM32CubeMonitor-Power also optimizes acquisition and parsing operations to flawlessly process the millions of measurements captured every second by the STM32 Power Shield without requiring expensive computers. Furthermore, this application includes a command line version so developers can use their favorite scripting language to perform custom test sessions and exploit all the information in their own applications.

The STM32 Power shield provides an accurate tool to measure the energy consumption of ultra-low-power devices. Together with the STM32CubeMonitor-Power graphical application, users will be able to analyse energy measurements and make better-informed decisions.
