SparkFun Serial Basic Breakout - CH340C and USB-C

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.
