Summary of DEVEBOX’S STM32H7XX-M DEVELOPMENT BOARDS FEATURES STMICROELECTRONICS’ STM32H7 MCUS
DevEBox’s STM32H7XX-M development boards use STM32H7 single-core and value-line MCUs for factory automation, connectivity, and security. Two variants—STM32H743VIT6 (2 MB flash, 1 MB RAM) and STM32H750VBT6 (128 KB flash, 1 MB RAM)—share the same form factor and features: multiple comms interfaces, display and camera support, Ethernet, USB OTG, ADCs/DACs, timers, watchdogs, RTC, power options, and operating range -40 to +85 °C. Boards measure 40 × 68 mm and are sold on Aliexpress and Banggood for $10.92–$18.20.

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.
