USB Driver
Click the links below to download the driver for your operating system. The USB-TTL programming board currently has two driver chip versions: CP210X (for CP2104 version) and CP34X (for CH9102 version). After extracting the compressed file, select the installation package corresponding to your operating system's bit version. (If you are unsure which USB chip your device uses, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may show an error during installation, but it is actually installed; you can ignore the error.) If you encounter issues with program downloading (e.g., timeout or "Failed to write to target RAM"), try reinstalling the device driver.
