Introduction 1
1 Introduction
The IMB-M45 is an ATX motherboard supporting Intel® Xeon™ E workstation and 8th and 9th Generation Intel®
Core™ i7/i5/i3 desktop processors, an Intel® C246 Chipset, and 5 PCIe expansion slots to provide a cost-
competitive embedded computing solution. With high-speed data transfer interfaces such as PCIe 3.0/2.0, USB 3.1
Gen2, and SATA 6 Gb/s (SATA III), dual-channel DDR4 memory up to 128 GB in four DIMM slots for industrial
automation applications, the IMB-M45 offers a significant competitive advantage for embedded computing
applications. The rugged I/O design enhances system flexibility with robust device compatibility, durable
connectivity, and extreme environment readiness.
