7.LED
Modes
Warning
This mode simply uses the LEDs to flash when warnings occur.
| Warning | LED Pattern | Notes |
|---|---|---|
| Arm-lock enabled | flash between green and off | occurs calibration or when unarmed and the aircraft is tilted too much |
| Low Battery | flash red and off | battery monitoring must be enabled. May trigger temporarily under high-throttle due to voltage drop |
| Failsafe | flash between light blue and yellow | Failsafe must be enabled |
Flash patterns appear in order, so that it’s clear which warnings are enabled.
Battery level
This mode binds the LED color to remaining battery capacity.
| Color | Capacity |
|---|---|
| Green | 100% |
| Lime green | 80% |
| Yellow | 60% |
| Orange | 40% |
| Red | 20% |
| Deep pink | 0% |
When Warning or Critial voltage is reached, LEDs will blink slowly or fast. Note: this mode requires a current sensor. If you don’t have the actual device you can set up a virtual current sensor (see Battery).
