Thank you for purchasing the Armadillo-420 Basic Model Development Set.
The Armadillo-420 Basic Model is comprised of the Armadillo-420 CPU board and the Armadillo-400 RTC Option Module.
The Armadillo-420 is a small form factor general purpose CPU board which along with the Freescale ARM9 processor "i.MX257", LPDDR SDRAM and flash memory, also incorporates interfaces which are often required for embedded devices, such as serial, LAN, USB 2.0, microSD and GPIO. Armadillo-420 keeps pin compatibility with the existing Armadillo-220 model while at the same time also offering improved performance and even lower power consumption.
The Armadillo-400 RTC Option Module can be connected to Armadillo-420 or Armadillo-440 to add RTC functionality.
Linux is employed as the standard operating system on Armadillo-420, providing access to a rich array of software resources. It is also possible to create and run original programs with C and other programming languages. For information on how to customize software, please refer to the "Armadillo-400 Series Software Manual."
This document contains precautions for use and explanations on how to use the software functionality available in the default state as at time of purchase. On obtaining the Armadillo-420 Basic Model Development Set, please check the operation of all hardware and the use of the default software.
The product name "Armadillo" will be used in descriptions that apply to the whole Armadillo Series for the remainder of this document.

This product uses semiconductor components designed for generic electronics equipment such as office automation equipment, communications equipment, measurement equipment and machine tools. Do not incorporate the product into devices such as medical equipment, traffic control systems, combustion control systems, safety equipment and so on which can directly threaten human life or pose a hazard to the body or property due to malfunction or failure. Moreover, products incorporating semiconductor components can be caused to malfunction or fail due to foreign noise or surge. To ensure there will be no risk to life, the body or property even in the event of malfunction or failure, be sure to take all possible measures in safety system design, such as using protection circuits like limit switches or fuse breakers, or system redundancy. |
1.6. Handling Precautions
Please pay attention to the following points when handling the product in order to avoid causing any irreversible damage.
- Areas Easily Damaged
The microSD connector and its cover can be easily damaged. Please be careful not to damage them by handling them with too much force.
- Modifications To This Product
Please take note that any modifications[] made to this product are not covered under warranty. Also, please ensure to undertake a full operational check of this product before carrying out any modifications or mounting connectors[].
- Mounting and Dismounting of Connectors While Powered On
Apart from hot-pluggable interfaces (LAN, USB), do not under any circumstances add or remove connectors while power is supplied to this product or peripheral circuits.
- Static Electricity
As CMOS devices are used in this product, please store it in antistatic packaging (such as that it was shipped in) until time of use.
- Latchup
Excessive noise or a surge from the power supply or input/output, or sharp voltage fluctuations can lead to the CMOS devices incorporated in the board causing a latch-up. Once the latch-up occurs, this situation continues until the power supply is disconnected, and therefore can damage the devices. Measures such as adding a protection circuit to noise-susceptible input/output lines or not sharing the power supply with devices that can be the cause of noise are highly recommended.
- Physical Stress
Please avoid strong physical stress such as drops or other impacts.
