Installing Driver

Finish the download. Now, let’s install the driver of KEYESTUDIO PLUS control board. Its chip is CP2102 serial chip. In general, the driver of CP2102 serial chip is included in ARDUINO version 1.8 and above. The driver will be recognized and installed as long as you connect board to computer with USB.


Some system can’t install automatically driver, you could install by hand. Open the device manager of computer and you will see a yellow exclamation mark which means the driver of CP2102 isn’t installed successfully.

double-click the“Cp2102 USB to UART Bridge Controller”and a window pops up, click“update driver”, as shown below:
