The ARM Cortex-M3 processor is the latest generation of ARM processors for embedded systems. It has been developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low power consumption, while delivering an outstanding computational performance and an advanced system response to interrupts. The ARM Cortex-M3 32-bit RISC processor features exceptional code-efficiency, delivering the high-performance expected from an ARM core in a memory size usually associated with 8- and 16-bit devices.

The board has the medium-density STM32F103 inside with an embedded ARM core which is compatible with all ARM tools and software. It combines the high performance ARM Cortex-M3 CPU with an extensive range of peripheral functions and enhanced I/O capabilities. STM32-H103 is a low-cost development board for the new ST Cortex-M3 based microcontrollers STM32F103RBT6. This board is the perfect solution for USB peripherals development. All microcontroller ports are available on extension connectors.
