Experiencing power and LED issues with your flight controller can be challenging. Here's an enhanced guide to help you diagnose and resolve these problems:
1. Check Connections:
Secure Wiring: Ensure all connections are firm and correctly oriented. Loose or incorrect wiring can disrupt power delivery.
Test with a Different Battery: Use an alternative, fully charged battery to eliminate the possibility of a faulty power source.
2. LED Status Indicators:
Red Indicator Light:
Steady Red: Indicates a normal power supply.
No Red Light: Suggests the flight controller isn't receiving power properly. In this case, inspect the power connections and consider consulting resources like SpeedyBee's troubleshooting guide.
Blue Indicator Light:
Blinking Blue: Signifies normal operation.
No Blue Light or Solid Blue: Indicates potential malfunction or a bricked state. To address this, you may need to enter DFU mode and reflash the firmware.
3. Test with Betaflight:
Connection: Connect the flight controller to Betaflight Configurator.
Error Check: Look for any errors or missing configurations.
Driver Issues: If connection fails, it might be due to driver problems. Running the ImpulseRC Driver Fixer can help resolve this.
4. Reflash Firmware:
Enter DFU Mode: If the flight controller is unresponsive, enter DFU mode to reflash the firmware. This process can often revive a bricked flight controller.
Firmware Compatibility: Ensure the firmware version is compatible with your specific flight controller model.
5. Voltage Calibration:
