The Express card from Shenzhen Hotin Development Ltd is a peripheral expansion device designed for laptops and mobile workstations, using the PCI Express x1 interface to add connectivity options such as Ethernet, audio, or wireless adapters. The product supports data transfer rates up to 2.5 Gbps per lane, consistent with PCIe 1.1 standards, and operates at 3.3V with a physical form factor of 75 mm by 54 mm, matching the ExpressCard/34 standard. It includes a metal shielding layer for EMI reduction and a plastic housing with reinforced insertion tabs for durability during repeated use.

The card is constructed with FR-4 substrate and gold-plated edge connectors, typical for industrial-grade expansion cards. Internal components use surface-mount technology with lead-free soldering, aligning with RoHS compliance norms.

The product is not branded with a proprietary name and functions as a generic interface module, intended for integration into custom systems or replacement upgrades.

End users include industrial technicians, field service engineers, and small-scale system integrators who require modular expansion in compact devices. The card is typically purchased in batches of 50 or more for OEM integration or repair kits. Packaging is in anti-static bags with bulk foam inserts, shipped in cartons of 100 units. Trade terms include FOB Shenzhen, with payment via T/T. Minimum order quantity is not stated and must be confirmed directly with the supplier.
