The CH340 driver chip is a USB converter chip, which converts USB to serial UART interface or to printer interface. 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 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. But don’t worry, it’s not that complicated as it sounds.Other Alternative to CH340 are CP2102 and FTDI. But the cost for these are more making your device costly. All three, Arduino UNO SMD, NodeMCU and USB to TTL converter, nearly get your work done.
Now here is the step by step illustration to install CH340 drivers on the Windows and Linux system.
Windows
(CH340 Datasheet and Software Chinese)
- Download the Windows CH340 Driver
- Unzip the file
- Run the installer from the folder that you unzipped.
- 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.
Linux
Drivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. If not you can download the Linux CH340 Driver (but we’d recommend just upgrading your Linux install so that you get the “built in” one).
With Arduino being an open-source electronics platform, their PCB designs are freely available, which means it is possible to get a generic Arduino board for much less than the branded boards.
Like when I purchased a 4WD chassis. Which also came with an unbranded Arduino UNO SMD.
What’s the difference with Arduino UNO SMD?The Arduino UNO SMD, uses a surface mount version of the ATmega328P instead of the through hole version.
But i had a problem with this generic board, when I came to use the board, I wasn’t able to communicate with the board via the Arduino IDE.
When I opened Device manager to double-check I was connecting using the correct COM port, it became clear that there was a missing driver as it was showing as “USB Serial”.
For any missing drivers that Windows isn’t able to automatically find and install and it isn’t clear where to get the drivers from as this was an unbranded board.The first step is to find the Hardware IDs of the device by right-clicking on the device > Details and Selecting Hardware IDs. In this instance I could search for the Hardware ID and see that it was for a “CH340 Serial to USB Adapter” which had the Hardware ID “USB\VID_1A86&PID_7523”.
It turns out it is very common for the generic Arduino UNO SMD’s to require this driver. For convenience please see below for a download of the driver.
NOTE: The download is provided for convenience and is provided “AS IS” without warranty of any kind, expressed or implied.To install this driver, right-click on the missing device and select “update driver”. Then select “browse my computer for drivers” and select the folder where you have downloaded and extracted the above download.
Once installation is complete the device is ready to use.
