Supports both C-C and A-C cables; standard solutions only support the latter. When using a C-C cable, the CCD chip receives more power and stability, preventing power shortages and disconnections during BIOS chip writing. Uses higher-cost recessed surface-mount electronic components with fixed pins, making them more durable for insertion and removal. Customized PCB fixtures and higher-cost fully automated SMT assembly ensure more stable electrical performance. Compact and elegant design, easy to store. The SuzyQ-Adapter is a professional-grade debugging and flashing adapter. It is suitable for Chromebooks/Chromeboxes and other devices without enterprise locks that support CCD functionality. Please ensure you need the necessary components before ordering. Thank you very much. How to use: Plug the adapter into a Chromebook or Chromebox that supports CCD functionality. Connect your own cable and, depending on your needs, connect it to another port on your device (usually for flashing) or another machine.
