Gyd-9e Datasheet - Fixed
It functions as a step-down (buck) or step-up converter depending on the setup, typically outputting a stable 7.5V to 9.6V to the LED strings.
| Problem | Likely Solution | | :--- | :--- | | | Check VCC and GND. Pull SDA/SCL up with 4.7k resistors. | | Yaw drifts constantly | The magnetometer needs recalibration. Run a calibration sketch. | | Very noisy readings | Add a 10µF capacitor between VCC and GND near the module. | | High temperature | Do not exceed 5V. Use 3.3V if available. | gyd-9e datasheet
: Connect to the positive terminal of your power supply. GND : Connect to the negative (ground) terminal. It functions as a step-down (buck) or step-up
