2.2 POWERING THE F1 LV EVALUATION PLATFORM
The PIC16LF1947 supplied with your F1 LV Evaluation Platform requires a supply
voltage of 1.8V-3.6V. Voltages above 3.6V will degrade or damage the device. There
are five ways to supply the necessary power.
1. Use PICkit 3
Select Power Supply Source via cross jumper configuration
2. External Power Source, J5
3. Use the Add-on Expansion Header, J6
4. Use an AAA Battery, J7, or
5. Use USB Cable, J8.
2.3 POWERING WITH PICkit™ 3
To power with the PICkit 3, perform the following steps:
1. Make sure a jumper or an ammeter is connected across J4.
2. Configure the PICkit 3 to supply a voltage between 1.8 and 3.6V. For proper LCD
contrast, the supply should be 3.3V.
3. Attach the PICkit 3 to the PICkit ICSP™ connector at the end of the board.
4. Activate the PICkit 3 power output.
FIGURE 2-2: POWERING FROM PICkit™ 3
Note: When powering from the PICkit 3, all power supply jumpers (J5 - J8) should
be removed.
