The input TYPE-C port has QC deception, and the deception output voltage should be less than or equal to the boost output voltage. The boost part uses XL6019, with continuously adjustable output. Adjust the R2 configuration resistor to change the input voltage. Adjust PR1 to change the output voltage, and seal the PR2 knob after adjustment. The voltage difference between input and output should be as small as possible, which is beneficial to improving power.
