Windows 10 / 7

  • Install CP210x VCP driver

Connect your USB UART module with HOST PC then, download and install USB to UART Bridge Driver.

CP210x USB to UART Bridge VCP Drivers

Once the driver is installed, you will find a COM PORT.

  • Set up a serial console program

PuTTY is one of common serial console programs.
You can download the putty.exe file for Windows here.

putty

Then, you need to set some basic options.

- Connection Type
Select the radio box, Serial of Connection type.
- Serial Line
Input the Serial line to COM Port number. You can get the COM port number from Device Manager menu.
- Speed (Baudrate)
Change the Serial speed to 115200 baudrate.

Every setting is now complete to run putty.
Open your serial port!

Linux (Ubuntu 13.10 or higher)

  • Install CP210x VCP driver

After your USB-UART kit is connected to HOST PC, check your usb serial node first.

$ lsusb
$ ls /dev/ttyUSB* -l

If CP210x VCP driver is not installed by default in your Linux Host PC,
the device node doesn't exist.
Then, install CP210x USB to UART bridge driver for Linux.

  • Set up a serial console program

Install serial communication program, minicom on your HOST PC.

$ sudo apt-get install minicom

Then, Set up minicom options.

$ sudo minicom -s

Select serial port setup from the menu.
Type 'A' to change the serial device, then edit the /dev/ttyUSB[number].
You will also set baud rate to 115200 8N1 and disable the Hardware Flow Control.

_____UART____
|Pin 4 - GND|
|Pin 3 - RXD|
|Pin 2 - TXD|
|Pin 1 - VCC|
\___________|

1.8V LVTTL for ODROID-U3/XU3/XU4/X2/X
3.3V LVTTL for ODROID-C1/C1+/C0/C2/W

RxD pin is input and TxD pin is output.

The VCC pin is not a power source but a reference voltage input.
It is used for detecting the IO voltage like a VIO or a VDDIO.
Support for I/O interface voltages down to 1.8 V is provided via a VIO pin.

Molex 5268-04a(2.5mm pitch) is mounted on the PCB.
Its mate is Molex 50-37-5043 Wire-to-Board Crimp Housing.
45 degreed corner edge is a mark for pin number 1.
