What is the use of stm32 development board?

STM32 development board is a hardware platform, which is used to learn the software development and hardware development of stm32 series single chip microcomputer. Nowadays, many electronic products are developed and tested by using STM32 development board, which is one of the commonly used tools in the field of automation control and embedded system. At the same time, it is also a practical tool for curriculum learning in major universities.

STM32 series is based on ARM Cortex-M3 core, and is specially designed for embedded applications requiring high performance, low cost and low power consumption. STM32 has three characteristics: a brand-new 32-bit MCU series based on ARM kernel, with advanced architecture, ease of use/freedom/low risk.

Low power performance advantages of STM32L:

STM32L series has added two low-power modes: low-power working mode and low-power sleep mode. By using ultra-low power regulator and oscillator, the microcontroller can greatly reduce the working power consumption at low frequency. The voltage regulator can meet the current requirements independently of the supply voltage.

STM32L also provides dynamic voltage rise and fall function, which is an energy-saving technology that has been successfully applied for many years, and can further reduce the internal working voltage of the chip when it is running at medium and low frequencies. In normal working mode, the current consumption of flash memory is at least 230μA/MHz, and the power consumption/performance ratio of STM32L is at least 185μA/DMIPS.
