TTL Converter Terminal Connection¶
This section shows you how to connect your Development Kit with a host computer to login to a terminal.
Wiring¶
If you are using the USB-to-TTL cable shipped with our modules, the Black wire always goes to GND or Number 1 Pin. The other side of course is plugged into your host computer.

Accessing¶
Linux¶
Note
This section was tested on Ubuntu 16.04.
- Install minicom:
sudo apt install minicom
- Power on the board.
- Use the TTL to USB Serial Converter cable to connect your computer with the board.
- Get the right ttyUSB instance:
$ ls /dev/ttyUSB*
/dev/ttyUSB0
- Connect minicom to the /dev/ttyUSB0 device:
minicom -D /dev/ttyUSB0 -t linux
Tip
You should consider using minicom with logfiles. They can be enabled with the -C option. An example would be: minicom -D /dev/ttyUSB0 -t linux -C ${HOME}/log/minicom/minicom_usb0_$(date +%Y-%m-%d).log
.
Note
By default you can quit minicom CTRL + A and then Q.
Windows¶
You will need a host computer with a terminal program, e.g. PuTTY.
The following example is for a Windows 10 host system.
- Power on the board.
- Use the TTL to USB Serial Converter cable to connect your computer with the board.
- Check the Device Manager to see as which COM the USB connected.
- For example, it would come up as COM9, configure PuTTY as follows:

- Hit “Open” and you should get terminal access to your board. Sometimes you have to hit the [Enter] key before you get an output.
Hint
If your computer is not recognizing the TTL to USB Serial Converter cable you might try installing this driver: http://www.ftdichip.com/Drivers/CDM/CDM21228_Setup.zip
