The Gigabyte B550I AORUS PRO AX is a compact, ITX form factor motherboard for AMD's Ryzen 3000 and 5000 series processors. Despite its small size, it packs a lot of features. Internally, it offers two full-size memory slots, four SATA ports, two M.2 connectors, and a PCI-Express x16 slot which can be used for a full size GPU or other expansion card (provided the chassis is large enough). Externally, the board provides analog audio input / output (no SPDIF, though), WiFi 6, Bluetooth 5.0, Gigabit Ethernet, and six total USB ports, including one USB Type C. There are also multiple video outputs present, but those only function if a processor with onboard graphics is installed.
