Speed up your Matter certification: STM32 platforms now certified for Wi-Fi and Thread

Related products:STM32 products and hardware tools

Building a Matter device? Give your idea a head start with two STM32 platforms certified by the Connectivity Standards Alliance (CSA) as Matter 1.5 Compliant Platforms. Choose Wi-Fi or Thread, reduce platform testing, and focus on the features that make your product different. 

 

Key benefits for developers 

  • Reduce certification effort: skip platform-only tests when you use the certified hardware and X-CUBE-MATTER 1.6.0 combination. Your end product still needs its own CSA certification, but a smaller test scope means lower costs and a faster path to market. 

  • Choose your connection: use Matter over Wi-Fi to connect directly to the home router, or Matter over Thread for low-power, mesh-networked devices. 

  • Keep your tools familiar: both platforms are certified with X-CUBE-MATTER 1.6.0 and share the STM32Cube ecosystem and toolchain. 

  • Simplify device setup: Bluetooth® LE enables easy, secure commissioning on both platforms.

 

Two certified platforms, one ecosystem 


1. Matter over Wi-Fi: STM32U5 + ST67W611M1 


Run your Matter stack and application on the NUCLEO-U575ZI-Q board. Its STM32U575ZI MCU combines an Arm® Cortex®-M33 core with TrustZone®, 2 Mbytes of flash memory, and 786 Kbytes of SRAM. 

Let the X-NUCLEO-67W61M1 expansion board handle wireless connectivity. Its ST67W611M1 module is a dedicated Wi-Fi 6 and Bluetooth® LE 5.4 network co-processor, connected to the host over SPI. Your MCU stays focused on application logic. 

Certificate ID: CSA26005MCPM0011-50

 

2. Matter over Thread: STM32WBA6 


The STM32WBA65I-DK1 Discovery kit is built around the STM32WBA65RI wireless MCU. It has an Arm® Cortex®-M33 core running at 100 MHz with TrustZone®, 2 Mbytes of flash memory, and 512 Kbytes of SRAM. On a single chip, it supports both Bluetooth® LE and Thread 1.4 over IEEE 802.15.4, with up to +10 dBm output power for extended range.
