DevEBox STM32H7 Development Boards are made for Factory Automation

When it comes to STMicroelectronics’ STM32H7 series, there are three product lines- Dual-core lines, Single-core lines, and Value lines. ARM Cortex-M7 based – STM32H7 MCU series is capable of delivering 1327 DMIPS/ 3224 CoreMark. These MCUs are designed for factory automation (HMI, process control, power management), connectivity & security (Alarm panel, Wireless Modules). To continue with the growth of the STM32H7 series, we have China-based MCUdev DevEBox’s STM32H7XX-M development boards taking a single-core line and a value line module.

The two STM32H7XX-M development boards use STM32H743VIT6 and STM32H750VBT6 core modules. The STM32H743VIT6 comes from a single core line that offers ARM Cortex-M7 gets up to 2 Mbytes of dual-bank flash memory and 1 Mbytes of RAM. While the STM32H750VBT6 module from the value line is one of the cost-effective STM32H7 devices featuring 128 Kbytes of flash memory.

STM32H7 Development Boards

These boards from MCUdev measure approximately 40mm x 68mm in size with the same peripherals. The manufacturer has produced both boards in the same form factor as the STM32F407VGT6 mini development board. Due to this, these models should be pin-compatible with each other.

How to get started?

STMicro has always provided complete software support for its core modules in the past. No different for the STM32H7 MCU series that comes with complete support of Arm Cortex-M architecture. Irrespective of the board (should have STM32H7 series core module), you can usethe STM32CubeH7embedded software package, which comes with many examples for this MCU series.

More details about the getting started guide, (in general for STM32H7 MCUs) can be found on STMicroelectronics’ website. There are also “user manuals” specific to the boards taken from the Banggood link below for STM32H750VBT6 (158MB) and STM32H743VIT6 (164MB).

More information on STM32H7XX-M Development Boards

For those interested in these boards, you can now buy them on Aliexpress or Banggood. These are priced at $10.92 for the STM32H750VBT6-based board and $18.20 for the STM32H743VIT6 module board.
