The VisionSOM-STM32MP1 family is a SODIMM-sized SoM based on the STMicroelectronics STM32MP1 (by default STM32MP157) application processor. The processor features a heterogeneous single or dual ARM Cortex-A7 cores together with an ARM Cortex-M4 core as well as a 3D Graphics Processing Unit (GPU) Open GL 2.0 ES compatible.

The dual Cortex-A7 and single Cortex-M4 based VisionSOM provides full flexibility to support real time application.

The VisionSOM-STM32MP1 is a general-purpose highly integrated SoM (System on Module). Module featuring high computation power and 802.11b/g/n Wi-Fi and Bluetooth v5.1 connectivity. The option of integrated, fully certified Wi-Fi and Bluetooth module simplifies the carrier board. The VisionSOM-STM32MP1 provides a variety memory configuration including flexible range of DDR3L, eMMC and SD memory card that meets our customers requirements.

The SoM supports connections to a variety of interfaces:

  • two high-speed USB on-the-go with PHY,
  • 10/100 Ethernet,
  • audio,
  • display with touch panel and serial interfaces.

In addition, the system supports industrial grade embedded applications.
