Technical Profile


SK401 is a PCIe/104 (StackPC) peripheral module designed for stacking system, expanding extra storage. The storage carrier can support either with two mPCIe or mSATA modules or one mSATA with one 2.5” SSD which can be stacked with other PCI/104 Express, PCIe/104, PCI/104 and StackPC modules.




The mSATA signal is transferred by PCIe/104 connector, however the board itself also carries PCI/104 interface to cater different expansion slot and create another stackable criteria. The storage module goes with standard mSATA ports which can replace any other mSATA storage devices. Combining with mSATA SSD modules can directly expand larger capacity to reinforce storage and performance. SK401 provides the power to 2.5” SSD which allows the users to assemble easily with embedded system. SK401 can not only be available as an independent mSATA SSD carrier but also as a complete storage solution.
