SparkFun Serial Basic CH340C Hookup Guide
The latest iteration of the SparkFun Serial Basic Breakout takes advantage of USB-C and is an easy-to-use USB-to-Serial adapter based on the CH340C IC from WCH. With USB-C you can get up to three times the power delivery over the previous USB generation and has the convenient feature of being reversible. The product works with 5V and 3.3V systems and should 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. It’s a great lower-cost alternative to the extremely popular FTDI Basic.
