Mini PCI Express Socket
ATTEND Technology's mini PCI and mini PCIe connectors were designed to provide a standardized interface for adding expansion cards to computer systems.
These connectors offer a compact form factor. The 119A series mini PCIe connector follows the PCI Express standard, providing a high-speed data transfer interface with one differential transmit pair and one differential receive pair. It has 1.5 V or 3.3 V power connections, totaling 52 pins. Both mini PCI and mini PCIe connectors are typically used for adding expansion cards such as Wi-Fi, Bluetooth®, mobile network, and SSD.
