Frequently Asked Questions
Q: What voltage range does this LED driver module support?
A: This constant current LED driver operates on a DC input voltage of 2.8V to 6V, making it compatible with common supply voltages including 3V, 3.3V, 3.7V (Li-ion batteries), 4.5V, 5V, and 6V power sources.
Q: How many LEDs can I connect to a single board?
A: The module can drive between 1 and 16 LEDs with a forward voltage of 2.8V–6V, as long as the total current does not exceed 1500mA (1.5A) and the total power stays within the 9W maximum rating.
Q: Can I control LED brightness using a microcontroller like Arduino?
A: Yes! The board supports PWM signal input for current adjustment, allowing you to connect it directly to the PWM output pin of an Arduino, ESP32, Raspberry Pi, or similar microcontroller to dynamically control brightness and manage operating temperature.
Q: Does this module support data transfer over its connection?
A: No — this module is designed for power delivery only. It does not support data transfer functionality.
