MadeForSTM32™ is a new quality label delivered by ST, which is granted after an evaluation process. It helps engineers identify third party solutions with the highest level of integration and quality for the STM32 microcontrollers' ecosystem. MadeForSTM32™ is offered to members of the ST Partner Program who want to go one step further in our collaboration, with the overall objective of contributing to a high-quality STM32 ecosystem.
The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
The STLINK-V3SET is a modular stand-alone debugging and programming probe for the STM8 and STM32 microcontrollers. It is composed of a main module and a complementary adapter board. The SWIM and JTAG/SWD interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board. The modular architecture of STLINK-V3SET enables to extend its main features through additional modules such as the adapter board.
The STM32L4+ series shatters the limits of processing capabilities in the ultra-low-power world
ST has enhanced STM32L4+ technology, providing more performance (up to 120 MHz), more embedded memory (up to 2 Mbytes of Flash memory and 640 Kbytes of SRAM) and offering richer graphics and connectivity features, without compromising on ultra-low-power consumption.
The following development tools enable flexible and comprehensive STM32L4+ evaluation and prototyping.
- 144-pin Nucleo boards: NUCLEO-L4P5ZG, NUCLEO-L4R5ZI, NUCLEO-L4R5ZI-P
- Discovery kits : 32L4R9IDISCOVERY, STM32L4P5G-DK
- Evaluation boards: STM32L4R9I-EVAL
