CH340G USB to Serial TTL Converter IC SMD
The CH340G is a USB-to-Serial (UART) converter IC manufactured by WCH (Jiangsu Qinheng Co., Ltd.). It enables communication between a computer and microcontroller-based systems via USB. It is widely used in Arduino boards and various embedded system applications.
General Features:
- USB 2.0 Full-Speed support
- UART interface support (TXD, RXD, RTS, CTS pins)
- Hardware flow control support (RTS/CTS)
- Baud rate up to 2 Mbps
- Low power consumption
- Works with external crystal oscillator (typically 12 MHz)
- Built-in USB protocol handling
- Driver support for Windows, Linux, and macOS (may require manual installation)
- Available in DIP-16 or SOP-16 package
- Typical Applications:
- Enabling USB connectivity on microcontroller development boards such as Arduino
- Projects requiring USB-to-serial communication between a computer and a device
- Using UART devices on modern PCs that lack traditional serial ports
- Programmer boards, data loggers, and test equipment
- Key Pinout Summary:
| Pin | Function |
|---|---|
| TXD | Transmit Data |
| RXD | Receive Data |
| VCC | Power Supply (3.3V or 5V) |
| GND | Ground |
| D+ / D- | USB Data Lines |
| XTIN / XTOUT | External Crystal Connections |
Advantages:
- Cost-effective and widely available
- Simple circuit integration for rapid prototyping
- Compatible with most operating systems
