Expandable Mini-PC runs Linux on quad-core AMD SoC

May 28, 2015 — by Eric Brown 5,610 views

CompuLab’s fanless Fitlet-H mini-PC has a quad-core 2.2GHz AMD A10 Micro-6700T SoC, up to 16GB RAM, internal SATA, dual HDMI, dual GbE, and dual mini-PCIe.

CompuLab’s Linux-ready Fitlet-H joins three other Fitlet models announced in January. These include the entry-level, dual-core (AMD E1 Micro-6200T) Fitlet-B, the quad-core (A4 Micro-6400T S), and the quad-core (A4 Micro-6400T) Fitlet-X, which adds support for CompuLab’s FACET (Function And Connectivity Extension T-Card) modular system expansion options.

The Fitlet-H uses AMD’s faster A10 Micro-6700T. The quad-core SoC adopts AMD’s Puma+ architecture, the successor to the Jaguar (Kabini and Temash) cores. Whereas the AMD SoCs on the earlier models started at 1GHz with a boost mode of 1.4GHz or 1.6GHz, the A10 Micro-6700T starts at 1.2GHz and boosts to 2.2GHz. Even with the addition of a GPU, the SoC still manages to maintain a low 4.5W TDP.

The Fitlet-H supports the same commercial, extended, and industrial temperature ranges as before, with the latter going up to -40 to 70°C. However, the new model offers “more thermal headroom,” which “allows operating the CPU at full load continuously regardless of environmental conditions and installing high-performance storage devices and extension boards,” says CompuLab. It also has a rugged aluminum case, which nearly triples the weight, although the footprint is a slim 16 x 16 x 2.5cm.


The Fitlet-H supports double or quadruple the RAM of earlier models, with 16GB, and it replaces the eSATA port with a regular SATA port with room for an internal HDD or SSD. As before, mSATA and microSD slots are available. RAM and storage said to be accessible through a one-screw service door.

Other features are very similar to earlier models, including WiFi ac, Bluetooth 4.0, a micro-SIM slot, and dual gigabit Ethernet ports. Once again, you get dual HDMI ports with audio, and audio interfaces including S/PDIF and line-out/in. The mini-PC offers more USB ports than on the other Fitlets, with a pair of USB 3.0 ports and six USB 2.0 ports.


The Fitlet-H provides dual mini-PCIe slots, one of which is shared with mSATA. There’s also an interface for CompuLab’s FACE expansion modules (shown below), borrowed from the earlier Fit-PC, instead of the newer FACET expansion implemented within the smaller Fitlet-X. The Fitlet-H mini-PC is sold as a barebones model that supports a variety of Linux and Windows versions, but it is optimized for Linux Mint.

“Many business customers are impressed with fitlet performance, but would like to trade the extremely small form factor of Fitlet in favor of more RAM, higher storage capacity, more connectivity and more thermal headroom,” stated Irad Stavi, Chief Product Officer at Compulab. “Fitlet-H is the ideal choice in these cases.”

Further information

The Fitlet-H Barebone is available now for pre-ordering from CompuLab for $436, almost twice as much as the other Fitlet models. No shipment date was listed. More information may be found at the Fitlet H product page.
