Driver Installation

Click on below link to download the driver for your operating system. After extracting the zip package, select the installation package that corresponds to the operating system bit number to install. (CH9102_VCP_SER_MacOS v1.7 may report an error during the installation process, but the installation is actually complete, just ignore it.) If you are unable to download the program properly (timeout or Failed to write to target RAM), you can try to reinstall the driver.
