- Some parts that use these drivers include the FTDI basic, Sparkfun Redboard and other Arduino boards that make use of a FTDI chip. And that's just to name a few. Install Drivers. To get started on a Mac, follow along with these steps. Note: My Mac is running Mac OS 10.9.5, however these steps should apply to all modern OS versions.
- A Windows message asks whether the driver has installed correctly. Connect your Nano. From Control Panel, open Device Manager and Ports. If installed correctly you should see an entry “USB-SERIAL CH340 (COMXX) In the Arduino IDE, go to: ToolsBoard (Select Nano) ToolsPort (Select the com port number found in Device.
Arduino bootloader (Windows & Mac OSX) The STM32 Blue Pill is pre-flashed with Arduino bootloader which allows you to download the sketch through the Type-C connector. NOTE: Using JLink / ST-Link dongle or USB to 3.3V TTL adapter to program the board will erase this bootloader.
TheCH340 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.

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).
