DevEBox’s STM32H7XX-M Development Boards Features STMicroelectronics’ STM32H7 MCUs

STMicroelectronics’ STM32H7 series are a couple of Arm® Cortex®-M7-based MCUs that claim to deliver 1327 DMIPS and 3224 CoreMark. They come in three product lines- dual-core lines, single-core lines, and value lines, and can be used in the design of many rich and complex applications including wireless modules, alarm panel systems, power management systems, etc. 

To further the growth of the STM32H7 MCU series is China-based MCUdev DevEBox’s STM32H7XX-M development boards designed for factory automation, connectivity and security applications. These new STM32H7XX-M development boards are built around two different STM32H7 chips of a single-core line and a value line module. They have the same form factor and share similar features except for the difference in their core modules.

The STM32H7XX-M development boards are readily available and can be purchased either on Aliexpress or on Banggood. You’ll get the STM32H750VBT6 module board for $10.92 and the STM32H743VIT6 for $18.20.

Just like other core modules from STMicro, the STM32H7 series also comes with complete software support of Arm Cortex-M architecture. You can use the STM32CubeH7 full embedded software package, which comes with several examples for the STM32H7 series.

User manuals specific to the boards are available on the banggood link mentioned above, while further details on the STM32H7 MCU series including a getting started guide can be found on the STMicroelectronics’ website.
