1>.Description:
 It is a boost module.This board is a booster board, and the output voltage is greater than the input voltage.When the output voltage is less than 4V,the onboard voltmeter will not work.

2>.Feature:
 1.It has a digital display to display voltage.
 2.Its conversion efficiency is high.
 3.It has an output voltage potentiometer to adjust the voltage in time.
 4.It has a display switch button to switch between input voltage display and output voltage display.

3>.Parameter:
 1.Product Name:Boost Module
 2.Input Voltage:DC 3.3~35V
 3.Input Current:9A(Max)
 4.Output Voltage:DC 3.5~50V
 5.Output Current:6A(Max)
 6.Output Power:100W (input voltage greater than 12V can reach the maximum output of 100W)
 7.Conversion Efficiency:96%(Max)
 8.Output Ripple:40mV(TYP)
 9.Range of Onboard Voltmeter:3~55V
 10.Work Temperature:-25℃~85℃
 11.Work Humidity:5%~95%RH
 12.Size:68*42*18mm

4>.Instructions for Use:
 1.The voltmeter can be turned off.Press and hold the switch for 4 seconds,and then it can be turned off by letting go.

 2.Input and output voltage measurement error calibration function,long press the switch for more than 4 seconds,after letting go,it will enter the voltage measurement error calibration function.

 3.The digital tube flashes to display the voltage calibration ratio value (range -5V~5V).At this time,short press the button to change this value (cycle between -5V~5V).

 4.When the voltage value displayed by the voltmeter is too high,lower the reference value (adjust to a negative number).

 5.When the voltage value displayed by the voltmeter is low,increase the reference value (adjust to a positive number).

 6.After adjusting to the reference value you want,press and hold the button for more than 2 seconds.After letting go,save the set value and return to the normal display voltage.The set correction value will take effect immediately and will not be lost after power failure.
