Onboard 5V Fan Connector
The FLY-Pi V3 provides an onboard 5V fan connector that can be used for cooling the host machine or other low-power components.
This connector is a ZH1.5 (2P) interface providing 5V constant power output. It continuously outputs voltage after power-on and does not support PWM speed control or software switching. Please only connect fans rated for 5V.
Wiring Instructions
Before starting any wiring, fully shut down the printer and disconnect the power supply. Confirm that the fan connector and the power supply are completely de-energized before plugging or unplugging the fan cable.
