MXM Connector


MXM Connectors
ATTEND's 125B-78C00 and 125A-78C00 are robust MXM connectors that offer a high-density PCIe® solution specifically designed to support advanced server system architectures. These connectors serve as an interface between the carrier board and the SMARC® and Qseven® or embedded GPU modules, transmitting all I/O signals. With a 0.50 mm pitch and 314 contacts, MXM3 connectors save PCB space, making them an ideal choice for compact designs. The MXM3 connector is a small form factor, low-power, high-performance connector supporting multiple high-speed peripheral applications. MXM interfaces are widely used in various mobile devices, including industrial controllers, in-vehicle computers, gaming, edge computing, and edge AI accelerators.
