U.3 (SFF-8639) PCIe Gen 4 16GT backs PCI Express Base Specification Rev 4.0 and comes with multiple built-in features SFF-8639 and 3.3V Hot Plug Power.

M.2 NVMe SSD Adapter backs voltage level shift, output SMBUS signals with 64K SMBUS, repeater buffer, and Hot plug. The unit contains wake# and CLKREQ# signals. It backs multiple different form factor M.2(NGFF) Type 2260-D2-B-M: 60mm(L) x 22mm(W), SSD such as Type 2242-D2-B-M: 42mm(L) x 22mm(W), Micro SATA Cables PN # U3-1694-M2, Type 2280-D2-B-M: 80mm(L) x 22mm(W). U.3 (SFF-8639) PCIe Gen 4 16GT comes with several built-in features such as SFF-8639, 3.3V Hot Plug Power, LED1 RED, LED2 GREEN, LED3 GREEN, fault alert, Back-to-Back (B2B) FET Operation, ESD HBM (Human Body Mode)/500V, control over output discharge, output overcurrent protection(OCP), and under voltage monitor. The unit provides protection against overcurrent and thermal shutdown. M.2 NVMe SSD Adapter backs SSD_Form_Factor_Version1_a and PCI Express Base Specification Rev 4.0. The unit is easy to utilize with Micro SATA Cables's PN # OCU-1735-U3 and Part#OCU-1690-GEN4. It is feasible with NVM Express 1.3a, PCI Express M.2 Specification Version 1.2, PCIe SFF-8639 Module Specification Rev 3.0, and SFF-TA-1001 Rev1.1.
