Low Profile Mezzanine for CompactPCI® Serial CPU Cards M.2 NVMe SSD Storage USB Type-C Front I/O

Available as a mezzanine add-on expansion board e.g. to the SC5-FESTIVAL and successor CPU carrier cards, the main purpose of the S20-NVME is to provide a mass storage solution, by means of an NVMe (PCIe x4) M.2 SSD module. M.2 (formerly NGFF) has been established as a standard by the PCI-SIG® and is very popular for industrial applications (IoT).
The S20-NVME accommodates an M.2 module with key ID M (PCIe x4), up to 22x80mm2 (2280). NVMe SSD modules are available from several manufacturers, with a maximum capacity of 2TB as of current. In addition, a front panel Type-C receptacle is provided on the S20-NVME, for use as USB 3.1 Gen 1 (5Gbps) host port (DFP). Dual screw locking Type-C cable connectors are supported. External devices attached can be sourced via VBUS up to 3A/5V.
The S20-NVME connects to the mezzanine expansion connector HSE1 of the CompactPCI® Serial CPU carrier board, maintaining the 4HP (20.32mm) total assembly height (low profile mezzanine module). The S20-NVME can be used together with an additional side card (8HP in total) attached to the CPU HSE2 connector.
