EAX-C246P

Series: EAX

Manufactured byAvalue
EAX-C246P Front

The Avalue EAX-C246P is an industrial-grade ATX motherboard designed for embedded and automation applications. It supports 8th and 9th Gen Intel® Core™ i7/i5/i3, Pentium®, Celeron®, and Xeon® E-2200/2100 processors with a TDP of up to 95W (note: for 9th Gen 8-core CPUs, TDP support is up to 35W). The board accommodates up to 128GB DDR4 2400/2666MHz DIMM memory with ECC support (depending on CPU). Key features include triple display outputs (1 x VGA, 1 x HDMI, 1 x DP++), dual Intel® Ethernet ports (1 x i211AT, 1 x i219LM Gigabit Ethernet), multiple USB ports (4 x USB 3.1 Gen2, 4 x USB 3.0, 2 x USB 2.0), serial interfaces (8 x RS-232, 2 x RS-232/422/485), GPIOs, and expansion options through 2 x PCIe x16 slots (supporting 1 x PCIe x16 or 2 x PCIe x8 by BOM option), 1 x PCIe x4 slot, 3 x PCIe x1 slots, 1 x PCI slot, 1 x M.2 (2242/2260/2280) M-Key slot supporting Intel® RST and PCIe x4 mode SSDs, and 1 x M.2 (2230) A-Key slot for Wi-Fi modules. With a standard ATX form factor of 304.8mm x 243.84mm, ATX power support, and operating temperature range of 0°C to 60°C, the EAX-C246P offers a robust solution for space-constrained environments.
