The latest Helix and Karbon fanless mini PC models from OnLogic are designed for the IoT and industrial markets. Equipped with the more powerful Celeron and Pentium processors, the Helix series comes in a more compact case, but it also offers fewer expansion options. The Karbon models, on the other hand, offer a more robust connectivity and expansion package, yet they only feature the slower Atom CPUs.
