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.
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.
These same form factor boards showcase similar features other than the onboard SoC.
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 use the STM32CubeH7 embedded 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).
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.

Very similar to a couple of WeAct modules – https://fave.co/3c5qLzS. I’ve ordered some of their ‘743 boards just for fun; I notice that their ‘750 module says “no longer available”. I prefer to have the schematics for these boards, see https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M/blob/master/docs/STM32H7XX_M_schematics.pdf for the DevEBox boards. Why do these Chinese vendors always provide sample code as Keil projects? Do they think that every hobbyist has paid for the Keil tools, or are they assuming widespread piracy?
The second one my friend
Where are the KEIL projects examples? Cannot find them.

Probably most of the Chinese hobbyists have a cracked version of the Kiel tools. It is quite easy to find in China…
Since I switched to CLion and sometimes STM32CubeIDE (it improved a lot last couple of versions), I never looked back to Keil.
There is another STM32H743VIT6 DevEBox with USB-C and 2 serial flash: https://fave.co/3iDkVXA
Or spend more for support?

Indeed, but too bad it’s such a huge footprint.
I wish there was a board with a similar footprint with an ethernet PHY and HS USB PHY. The Nucleo-H7xxx line is a bit too large for my use case. On the other hand, the Nucleo boards are offering a lot of bang for the buck dough.

Thanks, but none there as well with an onboard ethernet PHY. I guess I’ll have to use an external board.
Has anyone gotten this to run under Arduino? I am able to download code via STMCubeProgammer(DFU) but I can’t seem to get any output out of the board… I am using the DEVEBOX H743 version. I would be interested in any information anyone has. Thanks!
