Stm32 is a series of chips being developed and widely used in electronic and IoT projects. The research team designed and manufactured a versatile development kit using the central microcontroller Stm32f103rct6, high configuration, outstanding performance with 64 pins, ARM core 32-bit Cortex M3, the maximum frequency is 72Mhz, use with ten channels of 12-bit ADC; use two timers to generate PWM; communication standards: 2 sets of I2C, three sets of UART, 1 set of SPI, 1 set of CAN. In addition to the essential functions to support student learning, the kit also has advanced communication modules for IoT applications such as 800L SIM, AS32-TTL-100 LoRa, and RS485 communication. The equipment can collect, monitor environmental parameters, and support large-scale projects. This article will present the process of designing and manufacturing a multi-purpose kit and applying the product to satisfy flexible training, linking engineering disciplines, and developing in the direction of IoT.
