Transform your NVMe M.2 SSD into a U.3 (SFF-8639) with PCIe Gen 4 16GT/s adapter. Features incl. SMBus hot plug, voltage level shift & 64K SMBUS EEPROM.

The PCIe Gen 4 16GT/s Gen-Z (SFF-8639) to M.2 NVMe Adapter is a cutting-edge solution for users who need to convert M.2 NVMe storage to the U.3 (SFF-8639) interface. With a built-in SFF-8639 connector and pin-out defined by SFF-9402 Rev1.1, this adapter is designed to provide high performance and reliability for demanding applications.

This adapter features a built-in PWM 12V to 3.3V synchronous buck converter, providing power for M.2 NVMe SSDs. With a maximum output current of 5.5A, this adapter is equipped with output discharge control, over/under voltage protection, thermal shutdown protection, and ESD protection. The built-in 3.3V hot plug power with eFuse protection ensures the safety and stability of your M.2 NVMe SSDs.

The adapter supports the M.2 3.3V & 1.8V supply, M.2 VIO_CFG signal, M.2 PERST# signal, M.2 CLKREQ# signal, M.2 WAKE# signal, and PWRDIS signal. The M.2/1.8V to U.3/3.3V SMBCLK, SMBDATA level shift, isolated repeater, and hot-swap capabilities make this adapter a versatile solution for your storage needs.

With a built-in SMBus EEPROM 64KB, this adapter is compliant with NVM Express 1.3a, PCI Express Base Specification Rev 4.0, SSD_Form_Factor_Version1_a, PCI Express M.2 Specification Version 1.2, PCIe SFF-8639 Module Specification Rev 3.0, and SFF-TA-1001 Rev1.1. It supports the following form factors of M.2 (NGFF) SSDs: Type 2242-D2-B-M, Type 2260-D2-B-M, and Type 2280-D2-B-M.

LED1 (RED) blinking indicates M.2 active status, LED2 (GREEN) indicates 3.3V power ready, and LED3 (GREEN) indicates 1.8V power ready. The programmable current limit, inrush current slew rate, and thermal shutdown protection provide an extra layer of protection for your M.2 NVMe SSDs.

In conclusion, the PCIe Gen 4 16GT/s Gen-Z (SFF-8639) to M.2 NVMe Adapter is a highly advanced, reliable, and versatile solution for converting M.2 NVMe storage to U.3 (SFF-8639) interface. Whether you need to upgrade your storage or expand your system's capabilities, this adapter is a perfect choice.
