EMX-R680P
Series: EMX
The Avalue EMX-R680P is a Mini-ITX motherboard designed for industrial and embedded applications. It supports Intel® 12th/13th Gen Core™ i9/i7/i5/i3, Pentium®, and Celeron® processors with TDP up to 125W, utilizing the Intel® R680E chipset. The board accommodates up to 64GB DDR5 4800MHz SO-DIMM memory. Key features include quad display outputs (2 x DP++, 1 x HDMI 2.1b supporting 8K@60Hz, 1 x LVDS or eDP), four Intel® i226-LM 2.5GbE LAN ports, multiple USB ports (4 x USB 3.2 Gen2, 4 x USB 3.2 Gen1, 2 x USB 3.2 Gen1 via header, 2 x USB 2.0 via header), serial interfaces (2 x RS-232/422/485, 3 x RS-232), and expansion options through 1 x PCIe x16 Gen5 slot, 1 x M.2 (2230) E-Key for Wi-Fi modules, and 2 x M.2 (2242/2280) M-Key slots for SSDs. With a compact form factor of 170mm x 170mm, wide voltage input range, and support for Windows and Linux operating systems, the EMX-R680P offers a robust solution for space-constrained environments.
