The main modules of this system include measurement and display main control single chip GPRS. Metering uses a serial communication module to provide a serial port to send commands to the metering module for measurement, and the metering module sends back parameters such as voltage, current, and electric energy. GD32F350 receives and processes the display, stores it in the buffer, and then sends the stored data to Baidu Cloud through the GPRS module through the TFT LCD display. Then obtain the main parameters through the mobile APP.
i.MX RT1060 EVK is a 4-layer through-hole USB powered PCB. At its core is the i.MX RT1060 crossover MCU, implemented using NXP's advanced Arm® Cortex®-M7 core. This core runs at speeds up to 600 MHz to provide high CPU performance and excellent real-time response. Support for FreeRTOS™ is provided in the MCUXpresso SDK. Zephyr™ OS supports the i.MX RT1060 evaluation kit for developing IoT with a free, open source embedded operating system.

"Portable information board", as the name suggests, displays the information you want to display on a device (screen) that you carry with you. The inspiration for this idea was that I met many elderly people who were lost before, but some of them were too old, had poor memory, forgot where their home was, couldn’t find their family members’ phone numbers, etc. (Although there are only a few, they are still exists, and China’s population is aging increasingly, so the proportion will inevitably increase).
