The PCBA of Flash medal is a specially designed circuit board mainly used to achieve flash effects or related functions. Here is a specific introduction:

I. Basic structure

Flash medal circuit boards typically adopt a multi-layer printed circuit board (PCB) structure, which includes metal layers, insulation layers, and conductive layers. Through precise circuit layout and component configuration, achieve circuit control for flash effects.

II. Core functions

Mainly used to generate flashing effects, it may be applied in electronic toys, decorations, or specific electronic devices. By controlling the on/off or frequency changes of the circuit, dynamic effects such as flashing and gradient of LED beads can be achieved.

III. Working principle

Based on electrical control theory, the switch state of LED beads is controlled by a microcontroller or timer driven circuit. For example, using PWM (Pulse Width Modulation) technology to adjust the current frequency, thereby achieving flashing effects of different rhythms.

IV. Application scenarios

Commonly found in children's educational toys (such as flashlights), electronic DIY projects, or decorative devices that require dynamic visual effects. Its simple design and low-cost production also make it an ideal choice for popular electronic products.

V. Summary: The PCBA of flash medal achieves LED flash effect through multi-layer PCB design and electrical control technology, and is suitable for low-power, small-sized electronic devices or decorative scenes.
