Features
CAUTION
The EVB contains components that may be damaged by electrostatic
discharge. Observe precautions for handling electrostatic-sensitive devices
when using this EVB.
1.1
Peripheral daughtercards
The EVB has connectors / headers for various daughtercards that provide additional peripheral
functionality (see
Section 14, “User I/O and control
” for details). These are not supplied with the EVB and
may be sourced separately.
CAUTION
Daughtercards are usually not hot-swappable; ensure that the EVB is
powered OFF prior to fitting or removing a daughtercard.
