There are currently two driver chip versions, CP210X (for CP2104 version)/CP34X (for CH9102 version) driver compressed package. After decompressing the compressed package, select the installation package corresponding to the number of operating systems to install. (If you are not sure of the USB chip used by your device, you can install both drivers at the same time. During the installation process of CH9102_VCP_SER_MacOS v1.7, an error may occur, but the installation is actually completed, just ignore it.) When using it, if If the program cannot be downloaded normally (the prompt is overtime or Failed to write to target RAM), you can try to reinstall the device driver.
