PICDEM TM Lab Development Board User’s Guide
2. Using a 9V battery connected to connector BT1
Ensure that connect/disconnect jumpers J14 are in place.
3. A PICkit? 2 Programmer/Debugger connected to any one of the three PICkit?
Programmer/Debugger connectors J13, J12 and J6 (recommended for
low-power applications only).
Note:
When using the PICkit? 2 Programmer/Debugger as the power source,
the variable V DD potentiometer (R1) will not vary the supply voltage.
When using methods 1 or 2, each PIC ? microcontroller has an associated
connect/disconnect jumper that, when in place, enables the positive supply voltage to
the respective V DD pins. The V DD jumpers connect to the following PIC ? microcon-
troller sockets:
1. V DD 1 (J3) connects/disconnects supply voltage to the PIC ? microcontroller
populating U2.
2. V DD 2 (J4) connects/disconnects supply voltage to the PIC ? microcontroller
populating U3.
3. V DD 3 (J5) connects/disconnects supply voltage to the PIC ? microcontroller
populating U5.
Using methods 1 or 2 enables the use of the variable V DD potentiometer (R1) to control
supply voltages from approximately 1.3 to 5V. Rotating the potentiometer clockwise will
raise the supply voltage while rotating the potentiometer counterclockwise will
decrease the supply voltage.

CONNECTING THE PICkit ? 2 PROGRAMMER/DEBUGGER
The three PIC ? microcontrollers populating sockets U5, U3 and U2 have their own
PICkit? Programmer/Debugger (ICSP?) connectors so that each can be pro-
grammed or debugged individually. The ICSP? connect to the following PIC ? micro-
controller sockets:
1. ICSP1 (J6) connects to the PIC ? microcontroller populating U2.
2. ICSP2 (J12) connects to the PIC ? microcontroller populating U3.
3. ICSP3 (J13) connects to the PIC ? microcontroller populating U5.
The PICkit? Programmer/Debugger connects to the ICSP? connector as shown in
