STM32F103RET6 IC electronic components TFT true color screen development board core ARM CORTEX-M3 development board learning board

ARM core based on the latest of the STM32 Cortex-M3 STM32 Development Kit 32-bit Flash microcontroller family based on the breakthrough ARM Cortex-M3 core, which is a developed specifically for embedded applications, the kernel. Cortex-M3 core:
pushing the British company ARM core, committed to replace 8-bit / 16 bit microcontroller. Use THUMB-2 instruction set, 32-bit performance, 16-bit density, compared with the ARM7TDMI, Cortex-M3 core 35% faster, 45% code reduction. STM32 Cortex-M3 series of products due to the architecture on a number of improvements, including improved performance at the same time improve the code density of the Thumb-2 instruction set, a substantial increase in the interrupt response, and all the new features are both the industry Yun excellent power consumption levels.
