Customized for luminous yo-yos, kids’ educational toys and trendy stress-relief gadgets, this PCBA integrates centrifugal/rotation gravity sensor, RGB LED driver, mode switching, low-power control and charging management. The lights automatically activate via high-speed spinning for stunning dynamic lighting effects. Ultra-slim compact PCB fits plastic and metal yo-yo housings, with custom development and mass SMT production available.

I. Core Functions

• Centrifugal & Rotation Trigger Lighting: Built-in sensor IC switches on LED automatically when the yo-yo spins and cuts off lights at rest; keyless activation delivers smoother gameplay.
• Multi-Color Dynamic Lighting: Full RGB spectrum with preset effects: running chase, breathing, strobe, gradual color transition and marquee for spectacular spinning visuals.
• Power & Charging Management: Compatible with miniature rechargeable coin lithium cells or 3.7V lithium batteries with Type‑C charging. Full protection against overcharge, overdischarge, short circuit and overcurrent for safe durable use.
• Optional Mode Control: Concealed pushbutton available to toggle lighting modes and power; customizable brightness and animation speed.
• Rugged Structure: Simplified stable component layout with excellent shock & drop resistance to withstand high-speed rotation and collision during children’s play.

II. Core Advantages

• Extra tiny & slim PCB perfectly fits limited inner cavity of standard yo-yos;
• Highly responsive sensor enables instant spin-activated lighting for strong interactivity and fun;
• Low-power design ensures long battery runtime with cost-efficient layout ideal for large-volume toy orders;
• Customizable lighting firmware, sensor sensitivity and RGB color configuration;
• One-stop service covering circuit design, firmware programming, SMT assembly, flashing debugging and mass production.
