The particular Linux OS that the Mini 2 was designed to support is the latest Cinnamon flavor of the Mint variety, though it is compatible with other distros, as well as operating systems like Windows 10 or FreeBSD.

Within the all-metal housing of the 112 x 84 x 34 mm (4.4 x 3.3 x 1.3 in), 350 g (12.3 oz) mini computer is quad-core Intel Celeron (Apollo Lake) J3455 processor, which can fire up to 2.3 GHz and rocks Intel HD 500 graphics. The standard version comes with 4 GB of DDR3L RAM and 64 GB of storage, but a Pro model doubles both.

As with other members of the CompuLab stable, the MintBox Mini 2 doesn't have any noisy fans whirring away, but uses convection cooling through the all-metal housing to operate in temperatures between 0 and 45° C (32 to 113° F), and in relative humidity of 5 to 95 percent.

Connectivity is served up with two USB 3.0 ports and two USB 2.0, mini DisplayPort 1.2 and HDMI 1.4 that both support 4K monitors, two Gigabit Ethernet ports, a microSD slot for storage expansion, a serial port, Bluetooth 4.2 and 802.11ac Wi-Fi. It's also able to accept CompuLab's FACET cards, which give the Mint 2 more ports, or 4G capabilities, or more SSD storage. And the Mini 2 is compatible with all fitlet2 accessories and add-ons, including the fit-Uptime miniature Li-ion UPS power supply for up to 3 hours of stand-alone use between charges.
