  • Shock, vibration, and dust resistance

The mini PC supports Windows 10 IoT Enterprise LTSB and Linux Mint, and is compatible with other operating systems. Mounting options include and VESA and DIN rail mounts. The BIOS supports automatic boot on power resume, and settings can be saved to flash memory, so Fitlet2 mini PCs can work without RTC. It’s also possible to disable the power button, a remote power-button connector is present, and an optional TPM module can be added for hardware security.

Beside the switch from AMD to Intel, a new feature of Fitlet2 is support for what Compulab calls FACET cards (Function And Connectivity Extension T-Card), basically mPCIe expansion modules, 4 of which are currently available:

  • FC-LAN with two additional Gigabit Ethernet cards (for a total of four).
  • FC-PCIe and FC-CEM with support for both 4G cellular modem and WiFi
  • FC-USB adds 4 USB ports for a total of 8.

Other FACET cards are being working on for PoE, 2.5″ HDD/SSD, and optical LAN. Specifications and design guides for FACET cards for be found in the Wiki, so you could potentially design your own.

The company has also run GeekBench 3 on Fitlet2 computers, and compared to the previous generation Fitlet PCs, they offer both cheaper price, and better (CPU) performance.

Fitlet2 mini PC will be available from Compulab with 5 year warranty and 15 years availability. Pricing starts at $153, but there’s no buy link on their product page, and Fitlet2 is not listed on their Amazon Store yet.

Anyone who buys this should check:
– CompuLab have remembered to lock down the FDT and run CloseMnf
– Signed firmware updates are supported by BIOS

CompuLab have a not very good track record of shipping products with glaring security issues in their firmware. See: CVE-2017-8083 and CVE-2017-9457.

I hope they will improve, but from my experience security is the last thing they think about. Out of sight out of mind does not apply well to security issues.
