2.2 ESD Precaution
Please note that the LPC3250 OEM Board and OEM Base Board come without
any case/box and all components are exposed for finger touches – and therefore
extra attention must be paid to ESD (electrostatic discharge) precaution.
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.
Never touch directly on the LPC3250 OEM Board and in general as little as possible on the OEM Base
Board. The push-buttons on the OEM Base Board have grounded shields to minimize the effect of
ESD.
Note that Embedded Artists does not replace boards that have been damaged by ESD.
