Step 1

Connect your cable

The first step you need to do is connect your uploading cable. There are three parts:

  • Micro USB cable
  • UART cable
  • USB to UART adapter

Connect the adapter to one end of the UART cable. Then, connect the Micro USB end to the adapter.

Step 2

Programming mode

First, set your Smart Inventor Board to programming mode:

  1. Flip DIP switch 1 up to the “ON” position
  2. Connect the UART cable end of the download cable in the port on the lower right side of the Smart Inventor board.
  3. Connect the USB end to your computer. If you have USB-C ports, make sure you have an adapter nearby.
  4. Your blue LED should be flashing. If it’s not, tap the reset button below the DIP switches. Do not hold this button down because it will reset the board.

Step 3

Open your sketch

Next, open the Arduino IDE and open the sketch (or code) that you want to upload to the board.

Step 4

Select the correct board

Once you decide on your sketch, make sure you select the correct board in Arduino. Click on Tools > Board and then scroll all the way down to find your board.

Not sure which board is yours? On the front of your Smart Inventor Board, you should have an area near the center that says “Smart Inventor” with the version number, and that should match one of your options in Arduino. For example, if you have Smart Inventor V2, you should choose Rokit-SmartInventor-mega32_v2.

Step 5

Select the correct serial port

Find the serial port connected to your Smart Inventor Board:

  • For Mac look for “/dev/cu.SLAB_USBtoUART” or “/dev/cu.usbserial”
  • For Windows, look for a COM port number that is not COM1

Step 6

Upload the sketch

You’re almost done! Upload the sketch by clicking on the upload icon, which is an arrow pointing to the right. Once the file completely uploads to your Smart Inventor Board, Arduino IDE will display “Done uploading” in the bottom left corner. If you have any errors, make sure to resolve those code issues first.

Step 7

Initialize the program!

Finally, flip DIP switch 1 down to the “OFF” position to initialize your downloaded program. Done!
