The Upgraded DC-DC Boost Step-up Module with display has an operating voltage range from 5 to 32 volts, with an input voltage range of 3 to 32 volts (the boost below 5 volts typically works, but the digital display does not). It features a 5V to 40V thrust output voltage range. Built-in 4A high-efficiency MOSFET switch increases efficiency to 94% (LM2577 current is only 3A), and the ultra-high switching frequency of 400KHz allows for outstanding performance with small-capacity filter capacitors while reducing ripple and volume. (The LM2577 only operates at 50KHz.) and The input display indicator (IN indicator) is on when the digital display shows the input voltage, and the output display indicator (OUT indicator) is on when the digital display shows the output voltage.

 Specifications:

• With terminals, it is easy to use without a soldering iron, and the connection points of the soldering wires are reserved
• With overheat protection and short-circuit protection
• Size 65*39*14mm

• method: asynchronous rectification
• Input current: 4A (), no-load 18mA (5V input, 8V output, no-load less than 18mA. The higher the voltage, the greater the no-load current.)
• Conversion efficiency: <94% (the greater the pressure difference, the lower the efficiency)
• Switching frequency: 400KHz
• Output ripple: 50mV (the higher the voltage, the larger the current, the larger the ripple)
• Load regulation: ± 0.5%
• Voltage regulation rate: ± 0.5%
• Working temperature: -40 ℃ ~ +85℃
• Size: 65mm*39mm*14mm

Pinout of the Module:

• IN +: Input positive
• IN-: Input negative pole
• OUT +: Output positive
• OUT- : Output negative pole

Button function :

Each time the button is pressed, the voltage displayed on the digital Display switches between the input and output voltages. At the same time, the input LED and output indicator LED on the board are also switched, Press and hold the button for 2 seconds, and turn off the digital display.
