1.2.5 Indicator LEDs
The indicator LEDs indicate the status of operations on the PICkit 3.
1. Power (green) – power is supplied to the PICkit 3 via the USB port
2. Active (blue) – connected to the PC USB port and the communication link is
active
3. Status (one of three colors)
Success (green) – ready to start, or successful completion
Busy (orange) – busy with a function in progress, e.g., programming
Error (red) – an error has occurred

Note: Programming Serial EEPROMS devices requires a different programming
connector pinout. Pinouts for those types of devices are available in the
ReadMe file for the PICkit 3 included with the MPLAB X IDE software
(MPLAB X IDE Start Page, click on Release Notes and Support Documen-
tation).
Note: Blinking LEDs indicate additional information. For details, see Table 5-2.
