STMicroelectronics has extended its range of STM32 Nucleo development boards with scalable, small-form-factor variants to support the 32-pin members of its STM32 microcontroller family. The STM32 Nucleo-32 boards come with support from a choice of IDEs and access to mbed online resources. The STM32 Nucleo open platform is said to enable affordable prototyping using STM32 MCUs combined with a range of hardware plug-ins using Arduino Nano connectors.

Developers can also take full advantage of the STM32 software libraries as well as STM32Cube tools to facilitate software development and port designs from one STM32 variant to another. The STM32 Nucleo boards include the ST-LINK debugger/programmer, which enables drag-and-drop flash programming, so there is no need for a separate debug probe. Since the STM32 Nucleo boards are mbed-enabled, developers can make use of the mbed online tools and collaboration infrastructure at the mbed website.

There are currently three versions of the STM32 Nucleo-32 board based on the STM32F031, STM32F042 or STM32F303. STM expect the ultra low power STM32L0 and STM32L4 series to be supported in early 2016. The boards retail at $10.32 and are available through the usual distributors or directly from STMicroelectronics.
