Hi @jonicurn. I'm not sure I understood correctly what you mean by "not recognizing". Please add a forum reply here that provides a more detailed description to help us to understand it.

Do you see a serial port for the board after you connect it to your computer with a USB cable and then open the Tools > Port menu in Arduino IDE?

I do have port 3 and 4 to choose from but neither will work. i get "can't open device com 4"

Please perform this experiment to identify which port is your Mega Plus board:

  1. Disconnect the USB cable of the Arduino board from your computer.
  2. Select Tools > Port from the Arduino IDE menus.
  3. Take note of the ports, if any, listed in the menu.
  4. Close the Tools menu.
    :exclamation: The ports list is only updated when the Tools menu is re-opened, so this step is essential.
  5. Connect the Arduino board to your computer with a USB cable.
  6. Select Tools > Port from the Arduino IDE menus. - If a new port is listed in the menu, that is the port of your Arduino board.

Select that port from the menu and try uploading again.

If the upload still fails, or if no new port appeared after you plugged the Arduino board into your computer, add a reply here to let us know and we'll investigate the problem further.

No new port revealed even after disconnecting usb from computer, closing IDE, reconnecting usb and opening IDE/tools. Only com3 and com4, neither of which work.

If the IDE does not recognise the board the question is if Windows recognises it.

  1. Any changes in Windows device manager when you connect the board? If not, check cables.
  2. Any yellow exclamation marks in Windows device manager when you connect the board? The board uses the CP2102 serial-to-usb converter; did you install the drivers?

Checked cable/connection - good. Yes i do have a yellow exclamation mark in device manager. I choose to update driver then choose browse my computer. Then of the choices i get nothing works from that point

From the KeyesStudio site: Installing Driver

Other (if above does not help):

  1. You will need to find the driver for the CP2102 on the web. cp2102 driver - Google Search
  2. You can probably follow the instructions from Pololu - CP2102 USB-to-Serial Bridge Driver Installation
