mt3608 step up booster module

🔹 MT3608 Step-Up Boost Converter Module – 2A, Adjustable Output, 2V–24V Input

The MT3608 is a compact and efficient DC-to-DC step-up (boost) converter module capable of boosting input voltages as low as 2V up to a user-adjustable output up to 28V. It is ideal for powering 5V, 9V, or 12V devices from a single Li-ion battery or other low-voltage sources.

✅ Specifications:

• Input Voltage: 2V – 24V DC

• Output Voltage: Adjustable (up to 28V DC)

• Max Output Current: Up to 2A (depends on input/output voltage difference)

• Switching Frequency: 1.2MHz

• Efficiency: Up to 93%

• Onboard Potentiometer: Multi-turn for precise voltage adjustment

• Protections: Over-temperature, Over-current (SCP)

• Indicators: Power LED (optional on some modules)

• Dimensions: ~36mm x 17mm x 14mm

📦 Typical Applications:
✔️ Boost 3.7V Li-ion to 5V for USB devices / Arduino
✔️ 5V to 12V for LED strips or fans
✔️ Powering 9V / 12V sensors from a 5V source
✔️ Battery-powered portable electronics
✔️ LCD bias voltage generation
✔️ Solar charger and power bank projects

🔧 How to Adjust Voltage:

1. Power the module with the desired input voltage.

2. Measure the output voltage with a multimeter.

3. Turn the small blue potentiometer gently:

   • Clockwise: Increases voltage.

   • Counter-clockwise: Decreases voltage.

⚠️ Important Notes:

• Input Limit: Do not exceed 24V input.

• Current Limit: At higher boost ratios (e.g., 3V to 12V), the output current capacity will decrease (e.g., ~200mA).

• Heat: When running near maximum power (e.g., 12V at 1.5A), the chip can get very hot. Good airflow is recommended.
