5.Click finish and run Arduino IDE

Installing Driver

Install CP2102 Driver on Windows System

Now, let’s install the driver of keyestudio MEGA PLUS control board. Its chip is CP2102 serial chip.
Some system（WIN11） can’t install automatically driver but you could install it by hand.

Download CP2102 driver: https://fs.keyestudio.com/CP2102-WINDOWS
Or Download the driver of CP2102: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads

Click the link to download , and we unzip it to .

Unzip again and we will get the folder . Please remember the path of this folder for later use.

Right click Computer—– Properties—– Device Manager.

The yellow exclamation mark on the page implies an unsuccessful installation and you should double click img, then click “Update Drive…”to update the driver.

Click “Browse my computer for drivers” to find the downloaded Arduino software.

There is a DRIVERS folder in Arduino software installed package, please open this folder and check the driver of CP210X series chips.

Click “Browse…”, then search the driver of CP2102 and click“Next”.

After a while, the driver is installed successfully.

When opening the device manager, we will find that the yellow exclamation mark disappears, which means the driver of CP2102 is installed successfully.
