StarCB-STM32H757-STD Datasheet and Pinout

General description

StarCB-STM32H757-STD is a carrier board for the StarSOM-STM32H757 family of computer-on-modules, which are powered by one of the fastest MCU based on Cortex-M cores - STM32H757. A carrier board, together with a System on Module (SoM), makes a complete development platform similar to SBC. The carrier board houses the most common interfaces such as audio codec, USB, Ethernet, UART, RS485, CAN, ST-Link debugger, etc. A large variety of interfaces allows to use it as both a complete development platform or as a stand-alone end-product.
The carrier board connects with the SoM via a board-to-board, low profile connectors.
