Product Specifications: Input voltage: 4.3V-32V Output voltage: 5V-52V Maximum input current: 4A Maximum transmission efficiency: 94% Switching frequency: 400KHz Output ripple: 50mV Module Size: 69.8 X 38mm package: 1X DC Step Power Converter Module Button Description: 1. Input / Output Voltage Measurement Error Calibration: Press the button and hold for 4 seconds to release. The "IN" indicator is on (calibration input port) and the LED shows the calibration value (default is 0.0). You can short press the button to change the value ~ 0.5V), after setting, press the button, the last 2s, will enter the output port calibration, the same process to input calibration. After setting, press and hold the last button for at least 2 seconds to save the setting. 2. Display switch: Press the button for 1 ~ 4, you can turn the LED display on / off.
