NOTE
To alleviate confusion between jumpers and headers, all EVB jumpers are
implemented as 2 mm pitch, whereas headers are 0.1” (2.54 mm). This
prevents inadvertently fitting a jumper to a header.
CAUTION
Before the EVB is used or power is applied, please, fully read this user
manual.
Failure to correctly configure the board may cause irreparable damage.
Power must be removed from the EVB prior to:
•
Removing or installing daughtercards or other connectors.
•
Reconfiguring the board jumpers or switches.
