The project presented here is a bipolar stepper motor driver. It is based on the BD63731EFV chip, a low-power driver driven by a PWM signal. The project power supply voltage is 8~28V DC, and the rated output current is 3A. The input interface adopts CLK-IN drive mode, and the excitation mode corresponds to FULL STEP mode (2 types), HALF STEP mode (2 types), QUARTER STEP mode (2 types), 1/8 STEP mode, 1/16 STEP mode through the built-in DAC . In terms of current attenuation, the SLOW DECAY/FAST DECAY ratio can be set without any restrictions and all available modes can be controlled in the most suitable way. Additionally, the power supply can be driven by a single system, simplifying design.
The Bidirectional 400V-12V DC/DC Converter Reference Design implements an isolated bidirectional DC/DC converter based on a microcontroller. The phase-shifted full bridge (PSFB) with synchronous rectification controls the power flow from the 400V bus/battery to the 12V battery in buck mode, while the push-pull stage controls the reverse power flow from the low-voltage battery to the high-voltage bus/battery in boost mode. . This implementation uses a Texas Instruments (TI) 32-bit microcontroller TMS320F28035 on the low-voltage side to achieve closed-loop control of bidirectional power flow. This digital controller system implements advanced control strategies to optimally control power stages under varying conditions and provides system-level intelligence for safe and seamless transitions between operating and PWM switching modes.

This design is a 20A maximum power point tracking (MPPT) solar charge controller designed for solar panel input corresponding to 12V and 24V panels. This design is intended for small to medium power solar charger solutions, capable of operating from 12V/24V panels and 12V/24V batteries with output currents up to 20A. This design focuses on scalability and can easily be adapted to a 48V system by changing the MOSFETs to 100V rated parts. The user can also increase the current to 40A by using a TO-220 package version of the current MOSFET. This solar MPPT charge controller is designed with real-world considerations in mind, including reverse battery protection and software-programmable alarms and indications that are provided in the hardware but not configured. This design operates at greater than 97% efficiency at full load in a 24V system. For a 12V system, the efficiency is greater than 96%, which includes losses in the reverse-battery protection MOSFET.
STMicroelectronics provides users with a reference design based on L3751, suitable for DC-DC converters with input voltage 36-72V DC, output voltage 12 VDC, and 10A.
A smart wearable device based on the RSL10 development board officially provided by EEWORLD. This device is divided into two parts: the host and the slave. However, this MCU only has one UART, but in actual project requirements we need to use two UARTs. The organizer of this event gave five boards, so a board without a sensor is used as the SPI slave and will receive The command parses and uses AT commands to control the audio.

The home facilities on the RV include: lighting, sofas, seats, air conditioners, TVs, stereos and other electrical appliances. It is inconvenient to set independent switches for each appliance. The smart RV control system solves such problems. The deep learning speech recognition technology of artificial intelligence technology achieved a breakthrough in 2013, and the voice interaction method will occupy an important position for a long time after the technological breakthrough. Large-size touch screens are also the development trend of vehicle-mounted human-computer interaction equipment in recent years. This system uses speech recognition and display human-machine interface (HMI) as human-computer interaction equipment, and users control electrical appliances through voice and touch screen.
