Declaration of Electro Magnetic Conformity of the ruggbedBoard [To Be Decided]
phyCORE-A5D2x: RuggedBOARD System on Module (henceforth products) are designed for
installation in electrical appliances or as dedicated Evaluation Boards (i.e.: for use as a test
and prototype platform for hardware/software development) in laboratory environments.

Caution!
RuggedBOARD products lacking protective enclosures are subject to damage by ESD and, hence, may
only be unpacked, handled or operated in environments in which sufficient precautionary measures have
been taken in respect to ESD-dangers. It is also necessary that only appropriately trained personnel (such
as electricians, technicians and engineers) handle and/or operate these products.

RuggedBOARD products fulfill the norms of the European Union’s Directive for Electro
Magnetic Conformity only in accordance to the descriptions and rules of usage indicated in
this hardware manual (particularly in respect to the pin header row connectors, power
connector and serial interface to a host-PC).

Note:
Implementation of RuggedBOARD into target devices, as well as user modifications and extensions of
RuggedBOARD products, is subject to renewed establishment of conformity to, and certification of,
Electro Magnetic Directives. Users should ensure conformance following any modifications to the
products as well as implementation of the products into target systems.

IEC /EN** Vibration Test (Shockproof with Multiple drops from 5' (1.5 m) (TBD)

ESD Warning:

Electronic components and circuits are sensitive to Electrostatic Discharge (ESD). When
handling any circuit board assemblies including Pico Computer carrier assemblies, it is
recommended that ESD safety precautions be observed. ESD safe best practices include, but
are not limited to:
 Leaving circuit boards in their antistatic packaging until they are ready to be
installed.
 Using a grounded wrist strap when handling circuit boards, at a minimum you
should touch a grounded metal object to dissipate any static charge that may be
present on you.
 Only handling circuit boards in ESD safe areas, which may include ESD floor and table
mats, wrist strap stations and ESD safe lab coats.
 Avoiding handling circuit boards in carpeted areas.
 Try to handle the board by the edges, avoiding contact with components

Power Supply Warning:

Hardware Power Supply Limitation: Powering the board with voltages higher than 3.3V ± 5%
may damage the module. We recommend Supply voltage to SOM module from Carrier Board is
3.3V ± 5%.

In addition, for proper operation of the module into the target application also requires
connecting all GND pins common.

1. INTRODUCTION
1.1. Hardware overview
The ruggedBOARD-A5d2x for phyCORE-A5D2x modules is a low-cost, feature-rich software
development platform supporting the microchip Semiconductor phyCORE-A5D2x
microprocessors. Moreover, due to the numerous standard interfaces the ruggedBOARDA5D2x can serve as bedrock for your application. At the core of the ruggedBOARD phyCOREA5D2x is the phyCORE A5D2x System On Module (SOM), containing the processor, DRAM,
NAND Flash, power regulation, supervision, transceivers, and other core functions required
to support the phyCORE A5d2x processor. Surrounding the SOM is the ruggedBOARD
phyCORE-A5D2x carrier board, adding power input, buttons, connectors, signal breakout, and
Ethernet connectivity amongst other peripherals.
The phyCORE-A5D2x is a connector-less, BGA style System On Module (SOM) in a direct solder
form factor. Unlike traditional Phytec SOM products that support high density connectors,
the phyCORE-A5D2x SOM is directly soldered down to the ruggedBOARD-A5D2x using HalfHole Technology. This solution offers an ultra-low cost Single Board Computer for the
phyCORE-A5D2x processor, while maintaining most of the advantages of the SOM concept.
Adding the phyCORE-A5D5x into your own design is as simple as ordering the connectored
version and making use of our rugged Board’s Carrier Board reference schematics.

Fig. 9

The Industrial RuggedBOARD comes with an isolated Digital IOs(0-24V). The
ruggedBOARD provides four digital IOs that are designed for processing DC-signals with
up to 24 V DC. The digital output voltage depends on the input voltage of the board.
Input and output signals are routed to the CPU (SAM-A5D2x) through two discrete
optocouplers for galvanic isolation. Thus, it is possible to write and read the status of
every single GPIO of the ruggedBOARD simultaneously.

Please consider that the GPIOs do not have a separate current driver on board.
In case the GPIOs are used as outputs, the current is self-limited by the outputoptocoupler and should not exceed 750mA for each GPIO channel. These
outputs are low WARNING! side outputs.
