FUSE – FZ1
Fuse FZ1 will open during an over current condition. The cause of an over current condition
that opens FZ1 should be corrected before fuse replacement. FZ1 is a 5x20mm 500ma slow
blow type fuse.
Power Port
Power Port terminal block provides access to the +VIN, +5V, +3.3V, and GND (power ground)
supplies. The +VIN connection is not switched by the ON-OFF switch or fused and is directly
connected to the Power Jack. The +3.3V position can source 200ma to external circuits.
Applying +3.3V or +5V externally to power the board from the Power Port should not be
performed. If the user needs more power, an additional voltage regulator or source should be
applied with a common ground connected at the Power Port GND connection.

Power Jack
The Power Jack provides the default power input to the board. The jack accepts a standard
2.0 ~ 2.1mm center barrel plug connector (positive voltage center) to provide the +VIN supply
of +5 to +25 VDC (+9VDC typical).

PWR_SW – ON/OFF
The PWR Switch provides board power ON and OFF control. The +VIN supply from either the
PWR Switch or the POWER_PORT is applied via the switch.
