Click the link below to download the driver program that matches your operating system. Currently, there are two versions of driver chips, CP210X (suitable for the CP2104
version)/CP34X (suitable for the CH9102
version) driver program zip packages. After unzipping the package, select the installation package according to the bit version of your operating system for installation. (If you are unsure of the USB chip used by your device, you can install both drivers. CH9102_VCP_SER_MacOS v1.7
may show an error during installation, but it has actually been completed, so you can ignore it.)
