Mini PCIe RS232 expansion card
The SMUGDESK adapter converts a Mini PCIe slot into four DB9 COM ports for embedded industrial equipment. It targets system integrators who need reliable serial connectivity in harsh field environments. Industrial wide-temperature design keeps the card stable from -40°C to +85°C.
Builders needing rugged serial I/O
This card suits automation engineers adding PLC, sensor or data-collector links to compact box PCs. The premium control chip resists interference in electrically noisy plants. It is not for users who require USB, Ethernet or fibre interfaces, nor for desktop PCs lacking a Mini PCIe interface.
Operating temperature range
The -40 to +85 rating is the single spec that decides fit: if your enclosure stays within this window the card will operate without throttling or failure. Outside that range you must choose a different serial expansion method.

Questions about this item
How can I confirm the four COM ports are recognised after installing the card?
Check Device Manager on Windows or run dmesg on Linux; all four RS232 ports should appear as separate COM devices without errors.
What comes in the box and what must I source separately?
The card itself is included; you will need a compatible Mini PCIe slot on the host board and standard DB9 cables for each of the four ports.
Which version should I choose for a system that runs between -40 and 85 degrees Celsius?
This single model is rated for the full -40 to 85 range, so no alternate capacity or temperature variant needs to be selected.
