"It’s fanless and cooled by a large and thick heatsink, and most ports can be found on the rear panel: 12V DC jack, two USB 2.0 ports, a 10GbE RJ45, two USB 3.0 ports, one HDMI port, and two DisplayPort connectors. A look at the top shows one of the M.2 PCIe Gen3 x2 sockets (SSD2), an eMMC module slot, Power and Reset buttons, an RTC battery connector, a 4-pin 12V fan connector, and a 24-pin GPIO header. The bottom side features a single SO-DIMM connector and three more M.2 sockets. Note that SSD1 and SSD3 are PCIe Gen3 x2 sockets, but SSD4 is only connected to one PCIe Gen3 lane, so that’s something to keep in mind when connecting modules."
