StarSOM-STM32H757 Datasheet and Pinout
General description

The StarSOM-STM32H757 family is a small size and low profile SoM based on the STMIcroelectronics dual-core MCU, which features an advanced implementation of a ARM Cortex-M7 (up to @480MHz) and Cortex-M4 (up to @240MHz) cores.
The StarSOM-STM32H757 is a low power highly integrated SoM (System on Module) featuring high computation power, on-board Ethernet PHY 10/100, 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 design and is ideally suited for wireless application. The StarSOM-STM32H757 provides a variety internal and external memory configurations, including flexible range of SDRAM, and QSPI Flash that meets our customers requirements.
The SoM supports connections to a variety of interfaces: two high-speed USB on-the-go with PHY, dual Ethernet (single PHY on-board), audio, display with touch panel and serial interfaces. In addition, the system supports industrial grade targeting embedded application.
SoMLabs also provides a complete hardware and software development board for the SoM in the form of a carrier board and optional TFT display and touch panel.
