Unitronix announces a new fanless embedded system with an Intel Atom D525 / D425 processor, with up to 4GB DDR3. Based on the embedded concept, AR-ES6003FL has a variety of I/O features including four serial ports, six USB, two GbE, PCIe expansion, two SATA interfaces and a disk bay. This system has a MiniPCIe socket and a SIM card socket to enable WiFi and 3G connectivity.  This vehicle PC is configured so that the CPU and chipset are on the top of the board and the I/O slots are on the bottom of the board. Which increases the efficiency in heat transferring, as the heat sink is in close proximity to the CPU and chipset.
