The dual network ports support the teaming function, doubling the transmission bandwidth. The parameters of the two network cards are of each other and cards work independently. When of one network card fails, the system enables the backup network card to the normal operation of the system's network.COM port link can complete communication transmission with a small number of lines. Due to its simple connection, ease of use and high stability, it is widely used in computer communications, industrial automation control and data acquisition.Motherboard model: B365M-IPC_V100 MotherboardMotherboard version: Micro-ATX 248mm x 187mmCPU slot: LGA1151 (supports 6/7/8/9 generation CPU)Memory slot: 2*DDR4 64G (2133/2400/2666)Hard drive: 4* SATA3.0M.2 WiFi slot: 1*M.2_WiFi(NGFF)2242M.2 slot: 1*M.2_NVME(PCl-E3.0 X4)/NGFF(SATA3.0)2280Graphic Socket: 1*PCI-E3.0 x16, 1*PCI-E3.0 x1DisplayPort: 1*, 1*VGASound Card: Realtek ALC8975.1 channelNetwork: 1*Gigabit network card+1*2.5G network cardUSB Interface: 7*USB2.0,4*USB3.0(Front 5*USB2.0, 2*USB3.0)Other: F_PANEL, F_AUDIO, 4*F_COM F_SPK, 4*PIN CPU_FAN, 4PIN SYS_FAN, PS/2 keyboard, PS/2 mouseColour:blackMaterial:PCBPackage Contents:1 x MainboardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
