2025 Blue Bridge Cup IoT Design and Development Competition Training Platform Iterative Upgrade

The platform is designed based on the STM32WLE5 Sub-GHz wireless microcontroller. The chip has 256KB FLASH and 64KB SRAM memory, with a main frequency of up to 48MHz. It integrates the ARM Cortex M4 core and wireless communication unit, and supports LoRa ^® , (G) FSK, (G) MSK and BPSK debugging modes. The product is equipped with typical MCU peripherals such as buttons, indicator lights, debugger, OLED display, universal sensor interface, EEPROM memory, etc. It is powered by a single USB Type C interface and supports serial communication, program download and online debugging functions.

• High integration : Integrates typical functional modules to provide users with a complete experimental environment;.

• Communication mode : supports multiple debugging modes such as LoRa®, (G)FSK, (G)MSK and BPSK;

• Development ecosystem : Supports STM32 Cube MX/ ARM-MDK development tools and environment, eco-friendly;

• Scalability : It brings out MCU core peripherals such as TIM/SPI/I2C/ADC/USART, which is highly scalable;

• Flexible structure : Two solutions are provided: integrated and split, suitable for different scenarios;

• Easy to teach : The product has a simple design, clear interface and structure, and provides teaching materials and video courseware support. It is very suitable for practical teaching in colleges and universities, and can help students quickly get started and master the basic skills of IoT development.

The IoT Design and Development Competition Training Platform will be launched soon, and the supporting textbooks are being revised. Please stay tuned for follow-up introductions.
