Evaluation kit solution for Wi-Fi and Bluetooth🄬 modules for microcomputers (STM32) equipped with real-time OS


Turnkey solution to realize mounted Wi-Fi (wireless LAN) + Bluetooth is now ready

STMicroelectronics eForce Ubiquitous Murata

This solution solves "problems caused by combinations" which is one of the major barriers in the development of embedded applications, and "quickly" and "smoothly" supports the development of embedded applications utilizing wireless communications (Wi-Fi, Bluetooth). It also supports the creation of an advanced development environment by the STM32 Eval Board(evaluation board).

Mounting Wi-Fi Function for your embedded system is not the Goal of your development. It is important what you develop as application and what you add the value.

This kit includes all software needed to operate Murata modules connected to the STM32H743I-EVAL (evaluation board).

According to your request, you can get your specific function. You can reduce development cost and immediately develop.


Wi-Fi and Bluetooth development environments can be constructed quickly

Wi-Fi and Bluetooth development environments can be constructed quickly
  • Reduces Development Time
    Our Turnkey Solution is directly linked to mass production. Reduces "wastefulness" and "back tracking" common to prototype development as much as possible, which enables application development for commercialization.
  • Supports Low Power Consumption
    A power saving function is available by the combination of the STM32 Dynamic EfficiencyTM and Wi-Fi + Bluetooth.
  • Short Startup Time Improves Throughput
    Compared with Linux, the short OS startup time enables high-speed wireless operation. (Example) i.MX6 solo (Linux) about 20 [s], STM32H7 RTOS about 488 [ms] (Time from power ON to radio-wave transmission), and the speed of the throughput improved about 3 times compared with the STM32F429 microcomputers
  • High API Compatibility
    The API compatible Wi-Fi driver complies with modules of IEEE802.11 b/g/n/ac. The Wi-Fi module can also be updated easily in the future.
  • Functions According to Customer Specifications (Option)
    Supports the TX GLOM (transmission throughput improvement) function and DFS (AP mode) function as well. The route of the Wi-Fi and BT can be selected according to the specification.
  • Total Support
    Total support from actual product development to mass production and sales is possible using the ST Microelectronics's ST32CubeMX, and the "Wireless Function Evaluation Service" and "Radio Law Certified/Wi-Fi Certification Acquisition Support Service" provided by Murata Manufacturing.
  • WTS (Wi-Fi Certification Program) (Option)
    Supports Wi-Fi Certification Program for throughput measurement tools and 802.11AC.
