Zotac has launched a pair of mini-ITX motherboards for use with second generation AMD A-series APUs. The A75-ITX WiFi B-series and A55-ITX WiFi B-series boards work with FM2 socket processors and both include a single PCIe x16 slot, 802.11n WiFi and Bluetooth. The A75 and A55 in the product name indicate which AMD chipset the board uses, but other than that both boards have similar features. Two DDR3 slots allow for up to 16GB of RAM, three output connectors allow for a variety of compatible monitors, and four SATA ports can accommodate several hard drives and optical drives. The A75 board uses the SATA 6Gb/s standard while the A55 can only handle 3Gb/s. The A75 includes eight USB 3.0 ports and two USB 2.0 ports while the A55 features the opposite. Dual Gigabit Ethernet rounds out the A75, and the A55 has a single Gigabit Ethernet port.
