S42-MC

Low Profile Mezzanine Card for CPU Boards

M.2 SSD (NVMe PCIe x4 Gen3 or SATA 6G)
PCI Express^® Mini Card Sockets (2 x Half-Mini or 1 x Full-Mini)

The S42-MC is a low profile mezzanine module for EKF CompactPCI^® Serial CPU boards. It can accommodate either two PCI Express^® Half-Mini Cards, or one Full-Mini Card (PCIe^® Gen3 and USB 2.0), suitable e.g. for wireless applications such as WiFi or Bluetooth, or fieldbus I/O (CAN-FD). In addition, the S42-MC is equipped with an on-board M.2 PCI Express^® (NVMe) or SATA mass storage module socket, for operating system installation.

The S42-MC is suitable for EKF CPU carrier cards such as the SC4-CONCERTO or SC5-FESTIVAL, which are equipped with two HSE (high speed expansion) mezzanine connectors, for eight PCIe^® Gen3 lanes. The CPU carrier board and S42-MC side card assembly basically requires 4HP front panel width. If SMA antenna or any other front I/O connectors (e.g. D-Sub for CAN bus) are required, EKF offers custom specific 8HP front panel design for the assembly.
