Previously, the 7-PIN SATA DOM (Disk-on-Module) depended on an external power source. However, through innovative utilization of the SATA 7th PIN, this technology has progressed to eliminate the requirement for an external power cable. The SATA 7th PIN is now used to directly supply power, allowing the product to function without the necessity of an external power cable. This advancement provides the product with a broader range of power options, enhancing its convenience and adaptability for various applications.
