Directly addresses competition requirements for I2C protocols and embedded debugging, helping you tackle key tasks quickly and effectively. Onboard LINK debugger enables seamless programming, plus a double expansion port to connect official add ons such as temperature sensors, accelerometers, and keypads for handson skill mastery. Officially for the 15th Blue Bridge Cup Embedded Design Competition, this STM32G431RBT6 development board delivers competition ready performance for embedded design tasks. Hardware compatibility and proven reliability are demonstrated through participation in previous national tournaments. Use scenarios Competition practice and labs: Use the I2C capabilities and embedded debugging to simulate competition tasks, validate firmware, and refine performance in a structured learning setting. Rapid prototyping with sensors: Connect temperature sensors and accelerometers via the expansion port, program with the onboard LINK debugger, and test sensor data collection and real time responses. Human machine interface and control projects: Integrate a keypad to build and validate user input driven applications, leveraging the stable hardware platform for iterative development.
