4.7.2 Powering the Target

These are configuration essentials:

• When using the USB connection, MPLAB PICkit 4 can be powered from the computer but it can only provide a limited amount of current, up to 50 mA, at V_DD from 1.2-5V to a small target board.
• The desired method is for the target to provide V_DD since it can provide a higher current. The additional benefit is that plug-and-play target detection facility is inherited, for instance, MPLAB X IDE will let you know in the Output window when it has detected the target and has detected the device.

If you have not already done so, connect the MPLAB PICkit 4 to the target board using the appropriate cables (see Connecting the Target Board). Then power the target.
