fit-PC3 is designed around the AMD Embedded G-Series Fusion APU providing:

  • Dual-core 64 bit x86 CPU @ 1.0 - 1.65 GHz
  • AMD Radeon HD 6xxx GPU

The APU is supplemented by up to 8 GB DDR3-1333.



For a miniature fanless system - fit-PC3 provides extremely powerful graphics features

  • Dual-head DisplayPort (up to 2560×1600) and HDMI (up to 1920×1200) incl. audio
  • HDMI 1.4 and stereo-3D support in fit-PC3 Pro
  • DirectX 11, OpenGL 4.0, OpenCL
  • 1080p Blu-Ray playback support, UVD 3 engine with native H.264, VC-1, MPEG2, and DivX


Low Power

The fit-PC product line is recognized as the most power efficient in its category and fit-PC3 is no exception. The T40E model consumes just 7W at Windows 7 when idling, or up to 15W under full system load with dual head display. Each model's consumption reflects the performance and efficiency of the corresponding APU.

Out-of-the-box fit-PC3 provides a set of interfaces unmatched by any computer of a similar size:

  • Dual-head display HDMI + DisplayPort
  • Digital 7.1 S/PDIF and analog 2.0 audio, both input and output
  • Gigabit Ethernet
  • WiFi 802.11 b/g/n + BT combo with dual antennas
  • 2 USB3 ports + 2 USB2 ports
  • 2 eSATA ports
  • Bay for 2.5" SATA HDD
  • 2 mini-PCIe sockets / 1 mSATA
  • Serial RS232 port
  • IR Receiver

These interfaces are likely to satisfy the majority of applications, but not all. For example - what about network routing? This is where the uniqueness of fit-PC3 is revealed - in modularity.



Compactness and modularity are often contradicting design goals. Perhaps the most striking feature in the design of fit-PC3 is the degree of modularity and hardware serviceability without compromising on neither size nor looks of the device.


FACE Module (Function And Connectivity Extension Module)

The front-facing panel of fit-PC3 can incorporate any custom functionality and I/O. We call it FACE Module (Function And Connectivity Extension Module).


  • A FACE Module with 4 GbE ports and 6 USB ports for networking applications
  • Combine GPIOs, ADCs, DACs and serial ports for instrumentation
  • Add multiple frame-grabbers for a surveillance computer

FACE Module is implemented by an internal extension-board and a simple sheet-metal panel. CompuLab is designing multiple FACE Modules and opens the interface with complete documentation and reference designs for other companies to design their own FACE Modules.

The I/O brought to the FACE Module resembles extensibility of a desktop:

  • 4 PCI-E Lanes
  • 6 USB 2 + 2 USB 1.1
  • 25 GPIOs
  • 2 SATA
  • 2 SMBus
  • LPC


One-screw service door

Installing or replacing hard-disk, RAM and mini-PCIe modules (2 in fit-PC3) has never been easier. All it takes is opening one screw at the bottom of fit-PC3 and sliding-out the service door with the hard-disk attached. Then there is easy access to the 2 SODIMMs and 2 mini-PCI sockets.


Design and build

Most commodity small PCs follow identical design rules - a heat-sink on the CPU with a centrifugal fan blowing over it, all encased in a plastic housing. fit-PC design is radically different - focusing on miniaturization, robustness, reliability and silent operation rather than making the cheapest possible system


Thermal design

Design and build

All fit-PCs are designed for fanless operation at the smallest possible form-factor using the most reliable cooling mechanism in existence - heat dissipation through the housing itself. fit-PC3 is no different, but it takes the thermal design a step further.

  • Internal passive heat-spreader to eliminate hot-spots.

  • Power regulation based on both CPU and case temperature monitoring. If case temperature exceeds a threshold the CPU is underclocked until temperature is back within permitted range. The threshold can be configured in BIOS.


Industrial design

Each part of the metal housing of fit-PC3 is 3D modeled and produced by die-casting for perfect fit. The streamlined design under 1" thick may be misleading - but fit-PC3 is one of the toughest computers on the market - easily withstanding industrial, automotive and outdoors installations.


Embedded grade internals

CompuLab has been making embedded computer-on-modules for over 15 years. We know that using quality parts results in returning customers. All electronic components in fit-PC3 are embedded grade with long term availability and are RoHS compliant. The standard warranty on fit-PC3 is 2 years.
