KS0548(KS0548A)Keyestudio PLUS V2 Development Board

1. Description

Doing experiment with electronic products, we often program on the Arduino IDE development environment with Arduino series microcontrollers.

Keyestudio Uno PLUS control board is fully compatible with Arduino IDE development environment. It is as same as the Arduino UNO R3 board. Moreover, some improvements we made highly strengthen its function(as shown below). In order to wire efficiently, we equip with a 1m USB cable with type-c interface for you.

5. Install Arduino IDE and Driver

5.1 Download the Arduino IDE

Open the browser and search: https://www.arduino.cc/en/software, we will take WINDOWS system as an example to show you how to download and install.

You just need to click JUSTDOWNLOAD,then click the downloaded file to install it.And when the ZIP file is downloaded,you can directly unzip and start it.

5.2 Installing Driver

1、Windows System

Checking the driver

Connect the motherboard to the computer.

Open Device Manager，Open the device manager, if the prompt “Silicon Labs CP210x USB to UART Bridge (COMx)” appears to prove that the driver has been installed, please skip the “Driver installation” part.

Manual driver installation

Driver download

Windows System: Windows System driver

Connect the motherboard to the computer, open the device manager, if there is a yellow exclamation mark in front of the driver in the picture, it proves that the driver is not installed, please download the driver and install it manually.

2、MAC System

1 Checking the driver

Connect the development board to the computer, according to [Tools] —> [Port] to select the development board port (Note: If you can not confirm which port is the development board, please connect the motherboard to take pictures to record all the ports, and then unplug the development board to re-take pictures to record all the ports, and then compare to find the disappeared ports, and then unplug the motherboard after the disappeared ports is the port of the board, and then select the port on the line)If you can not recognize the port, please replace the computer USB port or around the phone cable to re-recognize the port, if it still does not work refer to the following steps to install the driver.
