3D Printed Photo Light Board

Overview

The finished
STL model can be used in a MakerWorld project. It can generate OpenSCAD source files with one click and then export them as an STL file usable by slicing software, with configurable parameters.
MakerWorld project address: https://makerworld.com.cn/zh/models/194195.

The schematic design
of the light board is nothing special; it still uses the PT8022W LED PWM driver chip, which has built-in touch functionality and is configured for stepless dimming. The
schematic indicates a 10Ω current-limiting resistor, but in actual use, it might not be bright enough. Two resistors can be connected in parallel to make a 5Ω resistor, resulting in an overall current of around 300mA and increased brightness.
The power supply design offers two selectable options: battery power or direct USB power. To use the desired power supply, simply solder one of R16 or R17.
However, I didn't consider battery space when designing the casing, so if you want to use a battery, you'll need to modify the casing yourself.
