In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.ĭrivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in.Run the installer from the folder that you unzipped.Now here is the step by step illustration to install CH340 drivers on the Windows and Linux system. All three, Arduino UNO SMD, NodeMCU and USB to TTL converter, nearly get your work done. But the cost for these are more making your device costly. Other Alternative to CH340 are CP2102 and FTDI. But don’t worry, it’s not that complicated as it sounds. The CH340 chip is used by a number of Arduino compatible boards NodeMCU and Some USB to TLL Converters to provide USB connectivity, you may need to install a driver to be able to detect your device to your PC. In UART mode, CH340 provides common MODEM interface signals, to expand UART interface of computer or upgrade common serial communication devices to USB directly. The CH340 driver chip is a USB converter chip, which converts USB to serial UART interface or to printer interface.
