2.6.8 Status LEDs

There are multiple status LEDs on the board that can be used to monitor the current state of the device.

Pictured below a couple of the available status LEDs. D3 is connected to NFAULT or GPIO2 of the BQ79718B-Q1 device. When a fault occurs, NFAULT will get pulled low and D3 will light up red.

D2 is connected to DVDD of the BQ79718B-Q1 device. When the device transitions to an active state, DVDD will go high and D2 will light up green.

Additionally, D5 and D6 are connected to DIO10 and DIO9 of the CC2662 device respectively. The user can define the functionality of DIO9 and DIO10 and use the LEDs to provide their desired status.
