Power Supply
The dsPICDEM™ 2 Development Board may be powered by a +9V AC/DC wall
adapter. A DC voltage regulator is provided so as to regulate the +9V input from the
wall adaptor and supply +5V to V
adapter. A DC voltage regulator is provided so as to regulate the +9V input from the
wall adaptor and supply +5V to V
DD
and AV
DD
pins on the dsPIC30F device. In order
to supply power to the board from a wall adaptor, the jumpers JP1 and JP2 need to be
installed and power should be supplied via the J4 jack. The PWR ON LED, D1 will
illuminate if the power has been applied to the board appropriately.
