Key Features

Description

The CMX34BT is an advanced PC/104 single board computer with a PCIe/104 stackable bus structure. As a part of RTD's PCI Express offering, this Intel Atom based CPU is exceptionally suited for intelligent systems requiring low power consumption in harsh thermal conditions. The surface-mount Type 2 PCI Express connectors enable users to stack multiple peripheral modules above and below the CPU. The 32GB onboard industrial grade flash drive makes this CPU Windows 10 ready.
