The CH340N Serial Breakout Board is an easy-to-use USB-to-Serial adapter based on the CH340G IC from WCH. It works with 5V and 3.3V systems and should auto-install on most operating systems without the need for additional drivers. If not you can find the drivers here. The Serial Basic uses the CH340G IC. as a result it can quickly and easily convert serial signals to USB. It’s a great lower-cost alternative to the extremely popular FTDI.
The pinout of the Serial Breakout mimics the common DTR/RX/TX/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).
