STM32 Nucleo-144 development board using STM32F746ZG MCU, supports Arduino, ST Zio and morpho connections
"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).

This work is a simple pedometer design. It mainly uses MEMS sensors to detect changes in human body posture. It uses a pedometer algorithm to implement a simple pedometer function. It uses an OLED screen as a display device and adds a GY-30 light sensor module to detect changes in brightness of the surrounding environment. To adjust the OLED backlight brightness in real time; at the same time, the on-chip RTC is used to realize the real-time clock function. Due to limited time resources, it can be expanded later to add heart rate detection, temperature, humidity and air pressure, voice playback and networking functions.
The MAXREFDES1160 is a 5V supplied, 2.75kVRMS, full-duplex and 500kbps isolated RS-485 module using the MAX14853. This reference design demonstrates how to build an isolated RS-485 module with a low-cost transformer to provide isolated power. A transformer from HanRun, the HR600755, is used in this design. The power supply on the reference design is derived from a single 5V source. Connect the design board to a USB port or connect an external supply from VDDA to GNDA to provide 5V power supply on the logic side (A). The integrated push-pull transformer driver and external transformer (TX1) generate an isolated supply for powering the isolated side (B) of the board.
