The hardware manufacturer Gigabyte has included a small mainboard with integrated CPU in its assortment. The GA-SBCAP3940 has an Intel Celeron E3940 processor soldered on. This 9.5-watt Apollo Lake generation quad-core is an upgrade to the two-year-old’s Celeron N3350. The motherboard measures 146 x 102 mm, making it more compact than a mini-ITX system.
Nevertheless, there is room for a SO-DIMM memory module. The system supports up to 8 GB of DDR3L RAM. In addition, two SSDs and WLAN modules can be installed in two M.2 slots – but only one at a time. Other drives fit two SATA-3 sockets. If an SSD is installed in the M.2 slot, however, one of the SATA sockets can not be used according to the manufacturer, as the ports share the bandwidth.
Many ports and passively cooled
There are also ports on the side: two USB 3.2 Gen 1 ports, four USB 2.0 ports and two RJ45 ports for Gigabit Ethernet. Screens are optionally connected to VGA or HDMI. The mainboard is equipped with a heat distributor at the bottom. This metal plate is supposed to make the passive cooled system more efficient. The product is compatible with your own SBC Fanless chassis, but can also be built into other enclosures.
The GA-SBCAP3940 is well suited as a stand-alone Linux system or as a small server – such as a NAS – through the ports. It can be ordered from various specialist dealers. However, the manufacturer does not quote a price. This is common for products that are more targeted to enterprise customers. The predecessor is no longer available, had cost around 150 euros at the time.
