SparkFun Serial Basic Breakout - CH340G

The SparkFun Serial Basic Breakout is a user-friendly USB-to-Serial adapter, utilizing the CH340G IC from WCH. This versatile device is compatible with both 5V and 3.3V systems and typically requires no additional drivers, offering a seamless installation process on most operating systems. The Serial Basic employs the CH340G IC to efficiently convert serial signals to USB, making it a cost-effective alternative to the highly popular FTDI Basic.

The SparkFun Serial Basic Breakout's pinout mirrors the common DTR/RX/TX/VCC/CTS/GND pinout found on a myriad of FTDI-to-USB derivatives. This allows it to be used as a general serial device for debugging, such as with a GPS module. The board features a jumper on the rear that controls the output voltage on the VCC pin. By default, the board outputs 3.3V and has 3.3V signals. However, adjusting this jumper to 5V will cause the board to output 5V on the VCC pin with 5V signals, providing flexibility based on your project needs.

Getting started with the Serial Basic Breakout is straightforward, with various resources available to assist you. These include a schematic, Eagle Files, a Hookup Guide, and a Datasheet for the CH340G. Drivers are also provided for Windows, Mac, and Linux operating systems. For those who wish to delve deeper into the device's capabilities and functionalities, the product's GitHub page offers a wealth of information.

The SparkFun Serial Basic Breakout is a testament to SparkFun's commitment to providing accessible, high-quality products for electronics enthusiasts of all skill levels. Whether you're a seasoned professional or a beginner just starting out, this device is an excellent addition to any electronics toolkit.
