The i2S-MP15x is a system core module based on ST’s STM32MP1 series of microprocessors. i2S-MP15x core board uses the STM32MP157AAA3 processor model, which uses ARM dual-core Cortex-A7 core and Cortex-M4 co-processor to provide better multimedia and real-time processing power. i2S-MP15x core board integrates CPU, DDR3L and Flash devices in a compact size of 70×105.5mm to meet most industrial applications, Internet of Things, portable consumer electronics, automotive electronics and other industries.

The i2S-MP15x core board provides the embedded Linux operating system, the kernel uses Linux 4.19 version. i2S-MP15x core board provides a lot of development information, including user manuals, base board PDF schematics, peripheral drivers, BSP source code package, development tools and other related information. It provides developers with a stable design reference and perfect software development environment, which can effectively help developers improve development efficiency, shorten development cycle, optimize design quality, and accelerate product development and time-to-market.

The i2S-MP15x core board provides a variety of mature software solutions, QT5.11 graphics framework software, web server, NTP, libmodbus and other rich software resources. The complete software architecture allows developers to focus only on the business application development of the product, effectively reducing the development cycle.

The i2S-MP15x processor on the core board is packaged as LFBGA448 and is compatible with several models of the STM32MP151 and STM32MP153 subseries of the STM32MP1 series.
