Ensure that the jumper at JP2 (Enable control) pins 2 and 3 are covered to shunt EN to GND, disabling the output.
Apply appropriate input voltage to VIN (J1-1) or
TP1 and GND (J1-2) or TP6. and be noted that the
board can't support hot plug-in. The input lines
should be connected between J1 and external power
source first before turning on the external input
power supply.
Move the jumper at JP2 (Enable control) from pins
2(EN) and 3(OFF), to pins 1(ON) and 2(EN) and make
JP1 pin 1 and pin 2 are covered, then the output
can be enabled.
Apply the loading to Vout (J2-1) or TP4 and GND (J2-2) or TP10.
