Download Datasheet


In-CarPC’s CQ30 series of fanless in-vehicle PCs offer outstanding functionality and performance in an extremely compact form factor.  The CQ30 series features a range of processors from Intel Celeron to Core i7, up to 8 GB RAM, plus numerous built-in options including cellular, GPS and GPIO.  Support for dual removable hard drives / SSDs, quad GbE LAN ports and dual cellular modems (with failover, load balancing and channel bonding options) make the CQ30 series ideal for applications involving bulk data capture and transmission (e.g. video capture and streaming) and/or where the reliability of cellular data connectivity is paramount. 

The fanless nature of the CQ30 series makes it suitable for extremely dusty environments, and the device's ruggedness is demonstrated by multiple MIL-STD-810F tests.  The CQ30 series has been awarded E-mark certification, making it fully approved for in-vehicle use, and carries a 2-year warranty as standard.

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 - for the operating temperature range of a specific configuration please contact us.

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.
