In-CarPC's CQ15 fanless PC is our entry-level fanless PC designed for vehicle environments, and offers outstanding functionality in an extremely compact form factor. The CQ15 features an Intel Atom D2550 processor with up to 4 GB RAM and numerous built-in options including cellular (with dual-SIM slots), GPS and GPIO. The fanless nature of the CQ15 makes it suitable for extremely dusty environments, and the device's ruggedness is demonstrated by multiple MIL-STD-810F tests.  The CQ15 has been awarded E-mark certification, making it fully approved for in-vehicle use, and carries a 2-year warranty as standard.

Microsoft Windows 7 Professional FES 32-bit**

Microsoft Windows 10 Pro 64-bit***

Other operating systems, including Windows Embedded options, are available upon request.

*Windows Embedded 8.1 Pro is technically identical to Windows 8.1 Pro, but with different licensing terms.  Windows Embedded 8.1 Pro will be available until Q3 2024.

**Windows 7 Professional For Embedded Systems (FES) is technically identical to Windows 7 Professional, but with different licensing terms.  Windows 7 Professional FES will be available until Q3 2024.

***Windows 10 Pro can be installed on the CQ15, but may not be suitable for all customers due to a lack of official drivers for some components.  


Integrated mounting flanges

Vibration & Shock

MIL-STD-810F (with SSD)


Passive cooling (fanless)


Width: 182* mm
Length: 168 mm
Height: 52 mm

*The width figure does not include the mounting flanges at base (total length occupied by mounting flanges: 30 mm)


1.4 kg (base specification)


Operating Temperature: -40°C to +70°C

Storage Temperature: -40°C to +80°C

The above temperature ranges are at base specification and with extended temperature RAM & SSD. Using standard RAM results in an operating temperature range of 0°C to +70°C. Using a standard SSD results in an operating temperature range of 0°C to +55°C. Some optional features also restrict the unit's operating temperature range.

In common with all passively cooled (fanless) computers, the PC should be installed in a location that allows cooling air to flow freely over the chassis fins.

Power Supply

Internal intelligent automotive power supply:
