## Long description

The Lenovo TC Tiny COM Expansion Card with BTB Connector II is a dedicated hardware solution engineered to extend the connectivity options of Lenovo ThinkCentre Tiny desktop systems.

Advantages
This expansion card offers a streamlined way to add legacy serial connectivity to modern compact workstations without requiring external adapters or bulky cabling. Its design is specifically optimized for the ThinkCentre Tiny form factor, ensuring that the internal layout remains organized and airflow is not obstructed. The use of a direct BTB interface minimizes signal loss and enhances the overall reliability of the serial communication link, making it a robust choice for long-term professional deployment.
Suitable for
Connecting legacy industrial equipment such as CNC machines or programmable logic controllers.
Integrating serial-based barcode scanners or receipt printers in retail environments.

Managing serial console access for network infrastructure devices.
When it may not be suitable
This card is not compatible with non-Lenovo desktop systems or ThinkCentre models that do not support the specific internal expansion interface. It is also not intended for users who require high-speed modern data interfaces like USB 3.0 or Thunderbolt, as its primary function is limited to legacy serial communication.

How to use
Installation should be performed by a qualified technician or an experienced user. First, ensure the ThinkCentre Tiny system is powered off and disconnected from the electrical outlet. Open the chassis according to the official service manual provided by the manufacturer. Locate the designated expansion slot on the motherboard and carefully align the BTB connector of the expansion card with the corresponding port. Press down firmly until the card is securely seated. Once installed, reassemble the chassis and power on the system. The operating system should automatically detect the new hardware, though you may need to verify the COM port settings in the Device Manager or BIOS/UEFI configuration.
What to consider before purchase
Verify the specific model compatibility of your ThinkCentre Tiny system.
Ensure that your software or hardware application specifically requires a physical serial COM port.
Check if your current system configuration has an available internal expansion slot for this card.
