Frequently Asked Questions

Q: What input voltages are compatible with this adjustable constant current LED driver module?

A: This LED driver module operates on a DC supply voltage of 2.8V to 6V, making it compatible with common sources such as 3.3V logic supplies, 3.7V Li-ion cells, 4.2V fully charged Li-ion batteries, and standard 5V USB power. This wide input range makes it highly versatile for battery-powered and USB-powered LED projects alike.

Q: How do I adjust the output current on this LED driver?

A: The output current is adjustable across a range of 30mA to 1500mA, typically via an onboard resistor or trim configuration. This allows you to fine-tune the current to precisely match your LED's rated forward current, ensuring optimal brightness and longevity for your LED components.

Q: Can this LED driver module be used with PWM dimming?

A: Yes! This module features built-in PWM (Pulse Width Modulation) control support, allowing you to connect a PWM signal to achieve smooth, stepless brightness dimming of your LEDs — ideal for dynamic lighting effects, user-controlled brightness interfaces, or automated lighting systems.

Q: How many units are available per order?

A: You can choose from single-unit (1 PCS), 5-piece (5 PCS), or 10-piece (10 PCS) quantity options, making it convenient whether you need just one module for a prototype or a batch for a larger production run.
