Dual-output USB fast-charge buck module with 6–32V input and 3–12V adjustable output, supporting multiple fast-charge protocols. Compatible with Raspberry Pi 4B and Jetson Nano.
DC input positive for the buck module; DFRobot specifies 6V-32V input voltage range.
DC input negative / return for the buck module input supply.
First USB fast-charge output channel; DFRobot states 2-way USB port output and 3V-12V protocol-adjusted output, default 5V.
Second independent USB fast-charge output channel; DFRobot states the 2 channels work independently.
