This SparkFun Serial Basic Breakout is an easy-to-use USB-to-Serial adapter based on the CH340G and takes advantage of the handy USB-C connector. With USB-C you can get up to three times the power delivery over the previous USB generation at 1.5A and and also solves the universally frustrating dilemma of plugging a USB cable in correctly, because it’s reversible! The Serial Basic works with 5V and 3.3V systems and posseses the capability to auto install on most operating systems without the need for additional drivers. The Serial Basic uses the CH340C IC to quickly and easily convert serial signals to USB.
The pinout of the Serial Basic mimics the common DTR/RXI/TXO/VCC/CTS/GND pinout found on hundreds of FTDI-to-USB derivatives. It can also be used as a general serial device for debugging (such as with a GPS module). There is a jumper on the rear of the board that controls the output voltage on the VCC pin. By default, the board outputs 3.3V and has 3.3V signals. Changing this jumper to 5V will cause the board to output 5V on the VCC pin with 5V signals.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- CTS
- CTS stands for Clear To Send, a serial flow-control signal that tells the other device it may transmit. It matters for reliable high-speed serial communication where buffers could otherwise overflow.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
