The non-silkscreened 0Ohm resistor next to U3 is used to configure the fan PWM positive and negative.
For DV05028B12U, use the 0Ohm resistor to connect pad closest to **inside** PCB (positive PWM).
The JP2 connector is used to connect the battery level indicator module, so **don't** solder XH2.54-2P.
The JP2 connector is used to connect the battery level indicator module, so **don't** solder PZ2.54-2X2P.
You can refer to the following procedure to verify that the PCB is working, and reproduce the soldering of J1 or U1 if there is an abnormality.
If you choose the DC version, you only need to solder C21 C22 JP1 JP3 JP4 R23 R24 R25 R26 U2 U3 VR1.
If you choose the Type-C version, You can refer to the following procedure to verify that the PCB is working, and refer FAQ if there is an abnormality.

### Assembly
Just assemble according to CAD drawings.
A total of three to five AWG24 wires are required:
- **Red** - Connect pin 1 of the toggle switch to pin 4 of PCB JP2.
- **Yellow** - Connect pin 2 of the toggle switch to pin 3 of PCB JP2 and the positive of the Li-ion battery level indicator module.
- **Black** - Connect pin 3 of the toggle switch to pin 2 of PCB JP2 and the negative of the Li-ion battery level indicator module.
Be careful to route these wires through CylinderFan-Electronic-KnobTop.stl and CylinderFan-Electronic-Potentiometer.stl and not to impede the rotation of the structure.
The other parts are simply assembled according to the CAD drawings.
Be careful **NOT** to allow parts to run over, wrap around, or rub the wires.
