Extended / Extreme Temperature Support

3.5"-SBC-APL V2.0 is a 3.5" single board computer (SBC), equipped with Intel® Atom® E3900 Series & Pentium® / Celeron® N- / J-Series.

Higher performance and power efficiency

The 3.5"-SBC-APL V2.0 provides up to a 30% increase in processing and graphics performance and a 15% increase in power efficiency over models with previous-generation Intel® processors.

Multi-functional integration

In addition, the 3.5"-SBC-APL V2.0 supports a highly-integrated M.2 expansion socket for USB, WWAN (3G, 4G), satellite navigation (GPS) and SSDs enabling developers to build more compact or thinner embedded devices.

Extreme temperature applications

Extended / extreme temperature models are also available allowing for operation under extreme high, low or radically fluctuating temperatures, which is common in industrial environments.
