Parameters:
Input voltage: DC 3.5V-30V(please leave margin in usage, or meter will burn)
Output voltage: DC 3.5V-30V(boost module; ensure input voltage < or = output voltage)
Continuous current: 6A(long-term work)
Max input current: 10A (peak)
Output power: 100W Max(U-in * I-in * Efficiency = U-out * I-out)
Voltmeter accuracy: +/- (0.5% +1 digit)
Static power consumption: typically around 15ma
Dimensions: 67x42x18 mm (L*W*H)
LED indicator: have
Anti-reverse protection: have

Working modes：
Output volt mode: LED indicator lights off when in output volt mode(default).
Input volt mode: press button to change to input volt mode and LED indicator lights on.
Alternate mode: press button again and input/output volt display in turn, each turn lasts for 3 seconds.(press one more time and return to output volt display mode)

Stop working mode:
Press button up to 4 seconds until LED display lights off, then please release the button and LED indicator lights on. At this time, module do not have memory function. Press the button again and LED voltmeter will work normally.
Module will automatically memorize current working stat us as power-on status if you long press button for 2 to 4 seconds, please check following memory mode:
[0] Default output voltage display when power on [1] Default input voltage display when power on [2] Default input/output voltage display alternately

Package includes:
1x LTC1871 Boost Power Converter+Voltmeter Display
