Mini CH343P Serial to USB Module

This module was designed to solve the problem of conventional USB-to-serial modules being unable to connect to Type-C ports.

USB-to-serial modules purchased online typically only connect to a computer via USB, often requiring a USB extension cable. To avoid this, a serial module with a direct Type-C cable connection was designed. This allows for most connection functions during debugging with just one cable (primarily because USB extension cables are expensive and difficult to use)

. The module uses a CH343P chip to convert the USB port to **3.3V TTL level** (if 5V TTL is required, please modify the circuit accordingly). The board provides both 5V and 3.3V power supplies. The 3.3V power is provided by the RT9013, and the **maximum output is recommended not to exceed 400mA** (the RT9013 is rated at 500mA, but considering heat generation, such a high current is not recommended). **Do not use in high-power applications such as motors.**

The CH343P uses a QFN16 package, and all capacitors on the board are 0603 packages. Neither of these packages is beginner-friendly; **it is recommended to use a heated platform and hot air gun for soldering**. The CH343P also has pads on the bottom, but the bottom GND pad is mainly for heat dissipation and soldering is not mandatory. If soldering skills are limited, **prioritize ensuring stable connections of the pins around the perimeter**.

A linear CCD camera-guided intelligent vehicle controlled by an STC32G128K microcontroller.

This intelligent line-following vehicle, based on the STC32G128K microcontroller, uses a CCD camera as a data collection sensor and gyroscopes and other attitude sensors for auxiliary operation. It controls the vehicle's line-following by controlling the PWM output of a DC motor.

This project aims to design an intelligent car capable of autonomous line following. By integrating multiple advanced sensor technologies and precise control algorithms, it achieves efficient and stable line following functionality.

The intelligent line-following car uses an STC32G128K microcontroller as its core control unit, fully leveraging its powerful computing capabilities and rich interface resources. A CCD camera is used as a data collection sensor, capable of capturing ground trajectory information in real time and accurately. The CCD camera sensor features high resolution and fast response, providing the car with clear and reliable visual input.

To further improve the car's operational stability and attitude control accuracy, attitude sensors such as gyroscopes are also introduced for auxiliary operation. The gyroscope can sense changes in the car's tilt angle and angular velocity in real time, providing the microcontroller with precise attitude data, thereby enabling more accurate dynamic adjustments.

In terms of power drive, the motor's speed and torque are precisely adjusted by controlling the PWM output of the DC motor. The application of PWM technology makes motor control smoother and more efficient, allowing for flexible adjustments to the car's speed and steering according to different road conditions and line-following requirements.

After the car starts, the CCD camera sensor continuously scans the ground trajectory, transmitting the collected data to the microcontroller. The microcontroller quickly processes and analyzes this data, combining it with data from attitude sensors such as gyroscopes to calculate the optimal motor control strategy. Then, it outputs corresponding PWM signals to control the rotation of the DC motor, enabling the car to travel accurately and stably along a predetermined trajectory.
