HPM-246UA
Series: HPM
The Avalue HPM-246UA is a single-socket ATX server board built on the Intel LGA1151 socket for 8th/9th Generation Intel® Core™ i7/i5/i3, Pentium®, Celeron® and Xeon® E processors (max. TDP up to 95W) with the Intel® C246 chipset, designed as a network-dense, manageable x86 platform for edge servers and networking appliances. With 4 x DDR4 2666MHz ECC/Non-ECC DIMM up to 128GB, onboard TPM 2.0 and IPMI 2.0 via an ASPEED AST2500 BMC, it pairs efficient Core/Xeon-E performance with seven Intel GbE ports in a 12" x 9.6" board. It provides flexible PCIe Gen3/Gen2 expansion plus a PCI 3.0 slot, 4 x SATA III, 7 x Intel I210AT 1GbE, triple DP++ (4K) display, and USB 3.2 Gen2/Gen1, running Windows 10 IoT or Windows Server 2016/2019.
