The new boards are fully compatible with the existing STM32 development ecosystem, including the range of dedicated plug-in application expansion boards that allow specialised features ranging from motor drives to motion and environmental sensors to be incorporated into the final application. They offer unlimited extension capability via three types of connector: in addition to the Arduino-compatible Uno and ST morpho connectors provided by existing Nucleo-64 boards, the new boards include an ST zio connector. Together, these three connectors give complete access to all of the STM32 general-purpose I/O pins, allowing implementation of any creative function. Some STM32 Nucleo-144 boards include Ethernet, as well as USB FS OTG ports to connect to local/wide area networks.
All of the STM32 Nucleo-144 boards include an integrated ST-Link debugger/programmer, which eliminates the need for a separate debug probe, and are compatible with the most popular development toolchains including IAR EWARM, Keil MDK-ARM, and GCC/ LLVM-based IDEs such as AC6 SW4STM32 or Atollic TrueStudio.
The new boards will be ARM mbed-enabled during Q2 2016, giving customers free access to ARM mbed online tools that do not require any software installation.
The first four boards (NUCLEO-F746ZG, NUCLEO-F429ZI, NUCLEO-F446ZE and NUCLEO-F303ZE) are available now at $23 for the Ethernet versions and $19 without Ethernet.
