●
RGB LED, (D3)
NOTE
The RGB LED is only available on the DA14699 daughterboard.
○
Green and Blue segments connected to dedicated LED driver pins
○
Red segment connected to a MOSFET driven by a GPIO
○
Circuit for powering the LED from either VBUS or VBAT
○
Option to power the LEDs from the 6.0 V available on the mainboard. If this option is chosen,
the SmartSnippets Toolbox measurement will exclude the LED current
