AOAA Kit - User’s Guide

Make it a habit always to first touch the metal surface of one of the USB or Ethernet connectors

for a few seconds with both hands before touching any other parts of the boards. That way, you

will have the same potential as the board and therefore minimize the risk for ESD.

Note that Embedded Artists does not replace boards that have been damaged by ESD.

2.3 General Handling Care

Handle the AOAA Board with care. The board is not mounted in a protective case/box and is not

designed for rough physical handling. Connectors can ware out after excessive use. The board is

designed for evaluation and prototyping use, and not for integration into consumer or industrial end-

products.

2.4 Code Read Protection

The LPC1769 and LPC11C24 have a Code Read Protection function (specifically CRP3, see

respective datasheets/user’s manuals for details) that, if enabled, will make the chip impossible to

reprogram (unless the user program has implemented such functionality).

Note that Embedded Artists does not replace AOA boards where the LPC1769 or LPC11C24

have CRP3 enabled. It’s the user’s responsibility to not invoke this mode by accident.

2.5 CE Assessment

The AOAA Board is CE marked. See separate CE Declaration of Conformity document.

The AOAA Board is a class B product.

EMC emission test has been performed on the AOAA Board. Standard interfaces like Ethernet, CAN,

USB, serial have been in use. General expansion connectors where internal signals are made

available (for example processor pins) have been left unconnected. Connecting other devices to the

product via the general expansion connectors may alter EMC emission. It is the user’s responsibility to

make sure EMC emission limits are not exceeded when connecting other devices to the general

expansion connectors of the AOAA Board.

Due to the nature of the AOAA Board – an evaluation board not for integration into an end-product –

fast transient immunity tests and conducted radio-frequency immunity tests have not been executed.

Externally connected cables are assumed to be less than 3 meters. The general expansion connectors

where internal signals are made available do not have any other ESD protection than from the chip

themselves. Observe ESD precaution.

2.6 Other Products from Embedded Artists

Embedded Artists have a broad range of LPC1000/2000/3000/4000 based boards that are very low

cost and developed for prototyping / development as well as for OEM applications. Modifications for

OEM applications can be done easily, even for modest production volumes. Contact Embedded Artists

for further information about design and production services.

2.6.1 Design and Production Services

Embedded Artists provide design services for custom designs, either completely new or modification to

existing boards. Specific peripherals and I/O can be added easily to different designs, for example,

communication interfaces, specific analog or digital I/O, and power supplies. Embedded Artists has a

broad, and long, experience in designing industrial electronics in general and with NXP’s

LPC1000/2000/3000/4000 microcontroller families in specific. Our competence also includes wireless

and wired communication for embedded systems. For example IEEE802.11b/g (WLAN), Bluetooth™,

ZigBee™, ISM RF, Ethernet, CAN, RS485, and Fieldbuses.
