Features:
1.Input and output voltage can be alternately displayed.
2.Switched on can be freely defined.
3.With a button to turn off the digital control function, reduce power consumption.
Working mode:
1.Output voltage mode: the default boot display ** output voltage mode. * LED indicator turns off
2.Input voltage mode: press the switch once to switch to the input voltage mode **. * LED indicator lights
3.Alternating pattern: Once again press the switch input / output voltage alternating 3S alternately display data (press again to return to the display mode of the output voltage)
Memory Mode:
*Long press the button more than 2S less than 4S digital tube display more information (in this case the key is released), the module automatically remembers the current state of the default power-on state.
*The digital tube close operation: long press button 4s until the digital tube display the contents of the LED is lit, the display section has been closed. Press the button again to restore the display.
[0] represents the default the boot display output voltage
[1] represents the default boot display input voltage
[2] represents the default open to input and output voltage are displayed alternately
Stop mode :
Press and hold the button until the display without digital display (above 4s) , release the button , LED lights on, LED voltage indicates the number is zero, then don't perform memory functions, click the button switch again, LED voltmeter work status open.
Data test (voltmeter turned on):
3.7V turn 5V/2A efficiency of 82.5%

Преобразователь позволяет повышать напряжение до заданного в пределах от 3.5 до 35 Вольт.
На плате установлен вольтметр с цифровым индикатором, который позволяет отображать как напряжение на входе, так и напряжение на выходе. Режим отображения переключается установленной на плате кнопкой.
По желанию, индикатор можно выключить, например, для экономии энергии.
С его помощью легко запитать монитор с входным питанием 19 Вольт от обычного аккумулятора, обеспечив себя благами цивилизации даже в лесу. (Хотя для этой цели лучше использовать два последовательно включенных аккумулятора с понижающим преобразователем - для повышения КПД).
Максимальный ток - 6 Ампер.
