Product Details
Purchasing and Inquiry
The CH340G is a USB-to-serial chip commonly used in electronic projects to provide a bridge between USB and serial communication. It is manufactured by WCH (Nanjing QinHeng Corp.), a Chinese semiconductor company. The CH340G is popular among hobbyists, makers, and electronic enthusiasts due to its affordability and widespread availability.
Key features and characteristics of the CH340G include:
USB-to-Serial Conversion: The primary function of the CH340G is to convert USB signals to serial (UART) signals and vice versa. This is particularly useful in microcontroller-based projects where a computer communicates with a microcontroller through a serial interface.
Driver Support: The CH340G requires a specific driver to be installed on the host computer to enable communication. The driver is usually provided by the manufacturer and needs to be installed before using the CH340G-based device.
Cost-Effective: One of the significant advantages of the CH340G is its low cost, making it an attractive choice for budget-friendly projects.
Compatibility: The CH340G is compatible with various operating systems, including Windows, macOS, and Linux, thanks to the availability of drivers for these platforms.
Baud Rate Support: It supports a range of baud rates, allowing users to configure the communication speed based on their specific requirements.
Voltage Levels: The CH340G typically operates at 5V, making it suitable for use with microcontrollers and other electronic components that use a 5V logic level.
Package: The CH340G is available in different packages, such as SOP-16, making it easy to integrate into various electronic designs.
Use in Arduino Boards: The CH340G is commonly found on inexpensive Arduino clones or Arduino-compatible boards, especially those produced in China. It serves as the USB-to-serial converter on these boards.
While the CH340G is widely used and can be a cost-effective solution for many projects, users should be aware that some operating systems may require manual installation of drivers, and the quality of drivers provided by different manufacturers can vary. Additionally, the availability of official support and documentation might be limited compared to more mainstream USB-to-serial converters.
