1. Preface
The Armadillo Series are small high-performance low-power general purpose boards which incorporate ARM CPU cores.
Linux (kernel 2.6) is employed as the standard operating system, providing access to a rich array of software resources and
proven stability. All boards include network interfaces as standard which, combined with the Linux network protocol stack,
enable simple development of network ready devices.
The Armadillo-400 Series models provide improved performance over existing products of the same class, while at the
same time also offering even lower power consumption. The Armadillo-400 Series is comprised of two products, the low
cost Armadillo-420 and the Armadillo-440 which can readily support multimedia functionality with the addition of an
expansion board.
Armadillo-400 Series boards have interfaces which are often required for embedded devices, such as serial, Ethernet,
USB, storage (microSD) and GPIO. In addition to these, multimedia functionality including LCD, touch screen and audio
interfaces can be added to Armadillo-440 via an expansion board. Other functionality such as a real-time clock and wireless
LAN can also be added with optional modules.
Armadillo-420 is available together with the RTC Option Module as the Armadillo-420 Basic Model. Armadillo-440
together with the LCD Expansion Board is known as the Armadillo-440 LCD Model.
This document covers the hardware specifications of the Armadillo-400 Series. For guidance on how to use the default
