CMX34BT: Intel® Atom E3800 Ultra Low-Power SBC
PCIe/104 Single Board Computer & Controllers
|
|
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. TPM (Trusted Platform Module) included for hardware-based cryptography. The surface-mount Type 2 PCI Express connectors enable users to stack multiple peripheral modules above and below the CPU. Standard CPU configurations do not include on-board flash (60GB SSD available for an additional cost).
How is the CMX34BT different from the CME34BT?
There are three primary differences between the CMX34BT and the CME34BT: ECC memory, the TPM version supported, and the Ethernet controller. The CME34BT features ECC memory, supports TPM 2.0, and uses an Intel I210-IT Ethernet controller. The CMX34BT features TPM 1.2, an Intel 82574 Ethernet controller, and does not include ECC memory.
