Name: Single-axis tracking board Voltage: 5-5.5VDC Current: less than 1.5A Interface: Power + - Motor M Principle: Uses a shield on the photoresistor. When light creates a shadow on the shield, a difference in photosensitivity between the two sides is detected, which controls the motor to find the balance point, aligning it to the center. Power supply requires a regulated 5-5.5V DC source with sufficient current up to 1.5A. The motor is a geared type; slower speed is preferred. The unit is compatible with JGY370 6V motor. At 5V power supply, the motor operates steadily under no load. If the motor speed is too high, slight oscillation may occur when aligning to the center, but jitter is minimized through a short delay anti-shake circuit. When connecting the motor to the board, polarity does not need to be observed. If the motor rotates in the wrong direction, simply reverse the motor wire connections. The board must be powered by a regulated 5-5.5V DC source and cannot be directly connected to a solar panel.
