3V-12V 3-way 300mAh Slow Breathing Light Module

3V-12V 3-way 300mAh Slow Breathing Light Module Electronics enthusiasts and decorators utilize this specialized controller board to create smooth, gradual fading and illumination effects for LED lighting setups. Consequently, it automatically modulates the output voltage across three separate channels to deliver an organic “breathing” transition without requiring manual microcode programming. Therefore, this compact module is an excellent hardware solution for upgrading static model displays, PC case modifications, and architectural accent lighting with minimal wiring overhead.

Key Features:

• 3-Way Independent Outputs: Drives up to three separate LED groups or loops with alternating or sequential fade patterns.
• Wide Input Range: Supports operating voltages from 3 V to 12 V DC, making it highly compatible with standard battery packs and USB power blocks.
• Onboard Driver Transistors: Features high-efficiency surface-mount switching transistors to support up to 300 mA load capacity.
• Smooth Fading Transitions: Employs an optimized fixed-frequency internal controller chip for flicker-free gradient dimming.
• Minimalist Layout: Eliminates complex external circuitry, offering a clean, plug-and-play installation structure for direct LED attachment.

Technical Specifications:

• Operating Voltage: 3 V to 12 V DC.
• Maximum Load Current: 300 mA total output rating.
• Control Mode: 3-way sequential or multi-phase slow-fade cycle.
• Drive Type: Low-side switching via independent surface-mount channels.

Mechanical Specifications:

• Model Identifier: YSJ-12BR silkscreened directly onto the PCB layer.
• Substrate Color: High-contrast green solder mask with gold-plated solder landing pads for reliable connections.
• Component Layout: Low-profile surface-mount technology (SMT) optimization for tight integration into compact spaces.

Dimensions:

• Length: ≈ 25.00 mm.
• Width: ≈ 16.00 mm.
• Height: ≈ 3.00 mm.
• Weight: ≈ 2.00 g (Ultra-light profile for weight-sensitive setups).

Pinout and Wiring:

• Input Pads (+ / -): Main power terminals connecting to the positive and ground rails of a 3V–12V DC source.
• Common Positive Terminal (+): Solder landing pad providing a shared anode connection for the output LED arrays.
• Channel Outputs: Three independent low-side cathode return pads configured to sink current for each breathing light circuit.

Commonly Used in:

• Cosplay Props: Adding slow-fading illumination to replica armor, glowing gems, or costume weapon modules.
• PC Modification: Powering ambient chassis lighting, custom distribution plate accents, and desk display setups.
• Scale Modeling: Enhancing model trains, sci-fi kits, and miniature architectural dioramas with realistic structural lighting behavior.

Applications:

• Ambient Lighting Display: Generating decorative multi-point luminance gradients across custom structural frames. However, drawing current significantly beyond the 300 mA threshold will overheat the drive transistors; therefore, system designers must integrate external current-limiting series resistors matching individual LED forward voltage constraints.

Equivalent Models:

• Single-Channel LED Breathing Dimmer Board: A basic variation restricted to a single synchronized light loop.
• NE555-Based PWM Fader: A classic discrete-component analog circuit offering manually adjustable potentiometers.
