Snowflake lamp (heart-shaped running water lamp hardware version)

1. Design reasons:
Because the original snowflake lamp circuit is difficult to weld, it is not suitable for beginners, and the design process of the heart-shaped running water lamp circuit is too simple, so I suddenly thought of combining the two and designed the snowflake lamp (heart-shaped running water lamp). Hardware version)
2. Snowflake lantern frame design and import
1. AUTOCAD draws the snowflake lantern frame.
First draw a hexagonal star (hexagonal star)
, draw the snowflake branches, then
draw the USB base in a circular array, and then add little details
2.DXF file Import
DXF layer 0 - board and frame layer
DXF layer silk screen - top screen screen
scaling ratio: 0.07
Import
3. Snowflake lamp PCB original layout and routing
1.
The overall component layout adopts a symmetrical layout, making full use of the limited space, and placing the LED lights in At the fork of the snowflake, just delete the last remaining LED.
2. The circuit connection
adopts upper and lower layers of wiring. The upper layer is laid with 5V copper and the lower layer is laid with copper GND. Since the snowflake light panel frame is relatively complex, the circuits are routed with arc degrees of freedom.
4. Physical verification
