LD06AJSA Adjustable Constant Current LED Driver Module 30-1500mA

The LD06AJSA Adjustable Constant Current LED Driver Module is an ultra-compact, high-efficiency current regulator designed to drive high-power LEDs safely and consistently. Operating within a versatile input voltage range of 2.8V to 6V DC, this module is perfectly optimized for single-cell Lithium-ion batteries (3.7V), 3.3V system rails, and standard 5V USB power sources. It prevents thermal runaway by delivering a highly stable, adjustable output current from 30mA up to 1500mA (1.5A), ensuring your LEDs operate at peak efficiency with maximum lifespan.

This driver board features a dedicated Chip Enable (CE) pin, allowing for seamless integration with microcontrollers like Arduino, ESP32, and Raspberry Pi. By applying a PWM (Pulse Width Modulation) signal to the CE pin, you can achieve smooth, flicker-free brightness dimming. Whether you are building custom DIY LED flashlights, solar-powered lighting systems, smart home illumination, or portable battery-operated lanterns, this lightweight module provides a reliable, high-performance constant current solution.

Features:

• Wide Input Range: Operates efficiently from 2.8V to 6V DC, making it highly compatible with Li-ion batteries and USB power.
• Adjustable Constant Current: Onboard precision potentiometer allows current regulation from 30mA up to 1500mA.
• PWM Dimming Support: Enable/CE pin accepts PWM signals for precise, high-frequency brightness control.
• Low Dropout Voltage: Minimizes power dissipation and maximizes battery run-time in portable applications.
• Integrated Protections: Built-in overcurrent protection and thermal shutdown safeguard both the driver and connected LEDs.
• Ultra-Miniature Footprint: Extremely compact design weighing only 0.7 grams, ideal for space-constrained DIY electronics.
