2 Introduction
2.1
Product Description
This credit card sized module is compatible to COM Express® pin-out Type 1. On 55 mm x 84 mm footprint nanoETXexpress-
SP is a perfect fit for the next generation of low power, ultra-mobile applications that require energy saving x86 processor
performance, high-end graphics, PCI Express and Serial ATA combined with longer battery life. These include handheld
devices for medical or multi-media applications, small mobile data systems and a host of new applications that have not
previously been possible due to size or power consumption limitations.
This mini COM form factor is 100 percent compatible with the COM.0 Type 1 with respect to connector location and pin
definition. Thus guaranteering scalability between modules. The Kontron nanoETXexpress-SP COM is based on the highly-
efficient Intel® Atom™ 5XX processor series and Intel® System Controller Hub single chip that combines the memory
controller, graphic engine and I/O in a single, space saving chipset design. With only one tenth of the Thermal Design
Power and one seventh the size of ULV processors at an identical performance, the nanoETXexpress-SP COM offers an
unprecedented power consumption / performance ratio for x86-based ultra-mobile designs.
The nanoETXexpress-SP with Flash and memory on-board support 1 PCI Express x1 (opt. 2 x1 if no onboard LAN), Serial
ATA, High Definition Audio, LVDS and optional SDVO. 10/100/1000 Gigabit Ethernet is designed in onboard for high
connectivity and 8x USB provides fast and sufficient interfaces for external peripherals. All above mentioned
requirements are supported by nanoETXexpress - small power - low size - high performance.

Naming clarification
COM Express® defines a Computer-On-Module, or COM, with all components necessary for a bootable host computer,
packaged as a super component. Interfaces will provide a smooth transition path from legacy parallel interfaces to LVDS
(Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA as well as PCI Express and
Serial ATA.

» microETXexpress® modules are Kontron's COM Express® modules in compact form factor (95mm x 95mm)
» nanoETXexpress modules are Kontron's COM Express® modules in mini form factor (55mm x 84mm)
2.3
Understanding COM Express® Functionality
All Kontron microETXexpress® and ETXexpress® modules contain two connectors; each of it has two rows. The primary
connector has two rows called Row A and Row B. The secondary connector has two rows called Row C and Row D. On
nanoETXexpress® modules only the primary connector Row A and Row B is used.
The primary connector (Row A and Row B) feature the following legacy-free functionality:
» Ethernet
» Serial ATA (SATA)
» USB 2.0
» LVDS/VGA and dual display video
» High Definition Audio (Azalia)
» LPC (low pin count) Bus
» PCIexpress
