[Verified] USB to camera fake battery power supply

Module description

• The input supports multiple protocols such as PD QC. The default input is 15V. If there is no 15V level, 12V will be used.
• When using a 15V 3A power input, the output power can reach a maximum of 40W (it will automatically enter protection after long-term use, and it can be restored by disconnecting the input and reconnecting it). The 20W power test runs stably for 3 hours for a long time.
• See the attachment for the matching 3D printed shell.

Component Description

• Decoy chip, FS312, if you need to use 15V, you need to use FS312H, connect a 140K resistor to decoy 15V, connect a 100K resistor to decoy 12V
• For the buck module mini560, you need to replace a resistor with a 12K resistor. Please purchase a 0603 resistor by yourself. For details, see the video https://www.bilibili.com/video/BV1Bh411z7kT/
• The 3D printed shell needs to be installed using M3x8 self-tapping screws. If it does not need to be disassembled later, hot melt glue or other glue can be used for installation.
