Regulable Buck-Boost Power Supply Module USB / 3.3V to 24V DPL

Description

What it is

The DPL buck-boost voltage regulator module is an electronic component that allows the conversion of the power supply voltage. It can increase or decrease the input voltage to achieve the desired output. It is adjustable via a potentiometer.

Features

• Voltage conversion buck-boost
• Adjustable via potentiometer
• USB power supply
• Adjustable output from 3.3V to 24V
• Current: check the datasheet

What it is for

This module is useful for powering electronic devices with different voltages. For example, it can be used to power an Arduino or an ESP32 with a voltage different from the standard 5V. It can also be used in DIY projects that require flexible voltage conversion, such as LED projectors or power supplies for electronic devices.

Tutorial: How to use DPL Buck-Boost Voltage Regulator Module

The DPL voltage regulator module is an essential component for projects requiring flexible voltage conversion, both from low to high and vice versa. It is ideal for beginner and intermediate makers who want to power devices with different voltages without complications.

What you need

• DPL Voltage Regulator Module
• Arduino Uno or compatible
• USB connection (for power supply)
• Capacitors
• Cables to connect

Steps

1. Connect the module to the power supply through the VIN and GND pins.
2. Connect the module’s output to the device requiring a regulated voltage using the VOUT and GND pins.
3. Check the desired voltage in the module’s datasheet to correctly set the output voltage.
4. If necessary, connect a capacitor between VIN and GND to improve power supply stability.
5. Connect the control pins to the Arduino microcontroller following the documentation provided by the manufacturer.
6. Write the Arduino sketch to adjust the output voltage if necessary.
7. Test the module output with a multimeter to ensure it matches the desired voltage.
8. Monitor the temperature during use and verify that it does not exceed safety limits.

Example code

void setup() {
  // Imposta il voltaggio di uscita (esempio: 3.3V)
  analogWrite(OUTPUT_PIN, desiredVoltage);
}

void loop() {}

Mini project

Create a portable LED projector with adjustable battery and USB power supply.

Common mistakes
