How to Use STEP-UP 2A MT3608 DC-DC USB-C: Examples, Pinouts, and Specs

The STEP-UP 2A MT3608 DC-DC USB-C is a compact and efficient boost converter module designed to step up a lower input voltage to a higher output voltage. It is capable of delivering a maximum output current of 2A, making it suitable for a wide range of applications. The module features a USB-C interface for convenient connectivity, allowing it to be easily integrated into modern systems. This component is commonly used in battery-powered devices, portable electronics, and DIY projects where voltage boosting is required.

• Powering devices that require a higher voltage than the available power source.
• Battery-powered systems, such as lithium-ion or AA battery packs.
• DIY electronics projects and prototyping.
• Portable USB-powered devices.
• LED lighting systems requiring higher voltage.

1. Connect the Input Voltage:

   • Use the USB-C port to supply input voltage from a USB power source.
   • Alternatively, connect a DC power source to the VIN+ and VIN- terminals.
   • Ensure the input voltage is within the range of 2V to 24V.

2. Connect the Output Load:

   • Attach the device or circuit requiring boosted voltage to the VOUT+ and VOUT- terminals.
   • Ensure the load does not exceed the maximum output current of 2A.

3. Adjust the Output Voltage:

   • Use the onboard potentiometer to set the desired output voltage.
   • Rotate the potentiometer clockwise to increase the output voltage and counterclockwise to decrease it.
   • Use a multimeter to measure the output voltage while adjusting.

4. Power On:

   • Once all connections are secure, power on the input source.
   • Verify the output voltage and ensure it matches the requirements of your load.

• Heat Dissipation: The module may heat up under high current loads. Ensure proper ventilation or add a heatsink if necessary.
• Input Voltage Limit: Do not exceed the maximum input voltage of 24V to avoid damaging the module.
• Output Voltage Adjustment: Always adjust the output voltage without a load connected to prevent overvoltage damage to your device.
• Polarity: Double-check the polarity of all connections to avoid short circuits or damage.

The STEP-UP 2A MT3608 can be used to power an Arduino UNO from a lower voltage source, such as a 3.7V lithium-ion battery. Below is an example setup:

1. Connect the battery to the VIN+ and VIN- terminals of the module.
2. Adjust the output voltage to 5V using the potentiometer.
3. Connect the VOUT+ and VOUT- terminals to the Arduino's 5V and GND pins, respectively.

// Example: Blink an LED using Arduino UNO powered by the MT3608 module
// Ensure the MT3608 output is set to 5V before connecting to the Arduino.

int ledPin = 13; // Pin connected to the onboard LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000);                // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);                // Wait for 1 second
}

1. Can I use the USB-C port and VIN terminals simultaneously?

   • No, use either the USB-C port or the VIN terminals, but not both at the same time.

2. What happens if I exceed the 2A current limit?

   • The module may overheat or shut down. Prolonged overcurrent conditions can damage the module.

3. Can I use this module to charge a battery?

   • While possible, it is not recommended unless you have additional circuitry to regulate the charging process.

4. How do I know the output voltage is correct?

   • Use a multimeter to measure the output voltage before connecting your load.

By following these guidelines and best practices, you can effectively use the STEP-UP 2A MT3608 DC-DC USB-C module in your projects.
