## Usage Instructions
1. **Input Voltage**: Connect the input voltage (4V to 38V DC) to the `VIN+` and `VIN-` pins.
2. **Output Voltage**: Use the onboard potentiometer to adjust the output voltage to the desired level.
3. **Load Connection**: Connect the load to the `VOUT+` and `VOUT-` pins.
4. **Cooling**: For high current applications (above 3A), attach a heat sink to ensure proper cooling.
5. **Protection**: Verify input polarity before powering the module to prevent damage.

## Example Applications
### 1. Battery Charging
Adjust the output voltage to match the charging voltage of your battery (e.g., 4.2V for a single Li-ion cell). Use additional circuitry for current regulation if necessary.
### 2. Voltage Regulator for Microcontrollers
Supply a steady voltage (e.g., 5V or 3.3V) for Raspberry Pi, Arduino, or other embedded systems.
### 3. LED Driver
Drive LEDs with a constant and adjustable voltage. Ensure to calculate proper current-limiting resistors.
