Name: Single-axis tracking boardVoltage: 5-5.5VDCCurrent: less than 1.5AInterface: Power + - Motor MPrinciple: Use a shield on the photoresistor. When the light irradiates the shield to form a shadow, when the photosensitive on one side forms a difference with the other side, the motor is controlled to find the balance point, that is, the center of the .The power supply uses 5-5.5V DC power supply, and the current is sufficient within 1.5A.The motor uses a geared motor, the slower the better, the owner uses for JGY370 6V , when the power supply is 5V, without load, the speed is stable. If the motor speed is too fast, it may cause the motor to sway left and right when it is aligned with the center of the , but it will not jitter. This circuit uses a short delay for anti-shake. When connecting the motor and the board, the positive and negative poles are not distinguished. During the test, if the motor is found to rotate in the opposite direction to the , just change the position of the motor wire. The power supply must be regulated 5-5.5V and cannot be directly connected to the solar panel.colour: blackMaterial: ABSSize: 36x16x1.2mmPackage Contents:2 x probe1 x MotherboardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
