The nPM1300 Power Management Integrated Circuit (PMIC) has three programmable LED pins, located on pin header P9.
Figure 1. LED schematic
The LED pins can sink constant current up to 5 mA. In addition, the pins can be configured in software to be open-drain connections. The table shows the default settings of the LEDs.
