Design of an STM32 EduTrainer Board For Industrial Application

The development of training modules based on microcontrollers is experiencing growth where currently the capabilities of a module must be at least the same as those in the industry and can be applied directly. One of the chip platforms that is expected to improve performance in the industrial world is the STM32 where this chip produced by ST Microelectronics has a high clock frequency, generally in the lowest range of 72MHz or more so it is clearly faster and more powerful. but there are different voltage levels between the microprocessor and the voltage level in the industry where in the industrial world the voltage level is 0-24 volts while the microcontroller has a voltage level of 0 - 3.3 volts, in this paper a main board has been designed which is powered by the STM32F103RET microcontroller and equipped with industrial Shield which allows the GPIO to communicate with industry standard voltage levels (0 and 24V) as well as industrial analog voltage levels 0-10v and current levels 0-20mA.
