Click the link below to download the driver for your operating system. Choose the installer that matches your OS bit version. (If you are unsure which USB chip your device uses, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but the driver is actually installed—just ignore the message.) If you encounter issues such as download timeout or “Failed to write to target RAM,” try reinstalling the driver.
