The InLine® M.2 to 2x serial 9-pin male interface card offers a compact and powerful solution for expanding a system by two serial RS-232 DB9 interfaces. The adapter uses a PCIe 2.0 interface (5 GT/s) and integrates the ASIX AX99100 controller, which is compatible with 16C950 UART for reliable and flexible serial communication. With a maximum transfer rate of up to 1 Mb/s, the card is ideal for industrial applications, embedded systems and serial ECUs. Automatic detection of the Lane configuration ensures seamless system integration. Power is supplied directly from the M.2 slot (3.3 V) so no additional power connection is required. Two low-profile brackets are included in the scope of delivery to allow flexible use of the card in different housings.
