Below are the key technical details of the Power Module GM V1.0:

The Power Module GM V1.0 has the following pin layout:

1. Connect Input Voltage:

   • Connect a DC power source (6V to 24V) to the VIN pin and GND pin.
   • Ensure the input voltage is within the specified range to avoid damage.

2. Adjust Output Voltage:

   • Use the onboard potentiometer connected to the ADJ pin to set the desired output voltage.
   • Measure the output voltage at the VOUT pin using a multimeter for precise adjustment.

3. Connect the Load:

   • Connect the device or circuit to be powered to the VOUT and GND pins.
   • Ensure the load does not exceed the maximum output current of 2A.

4. Power On:

   • Turn on the input power supply and verify the output voltage and current.

• Always verify the input and output voltage levels before connecting sensitive devices.
• Avoid exceeding the maximum input voltage (24V) or output current (2A) to prevent damage.
• Use proper heat dissipation methods if the module operates at high currents for extended periods.
• Ensure proper polarity when connecting the input and output terminals.

The Power Module GM V1.0 can be used to power an Arduino UNO. Below is an example setup:

1. Connect a 12V DC power source to the VIN and GND pins of the module.
2. Adjust the output voltage to 5V using the potentiometer.
3. Connect the VOUT pin of the module to the 5V pin of the Arduino UNO.
4. Connect the GND pin of the module to the GND pin of the Arduino UNO.

Here is a simple Arduino code example to blink an LED while powered by the module:

// Simple LED Blink Example
// Ensure the Power Module GM V1.0 is set to 5V output for Arduino UNO

const int ledPin = 13; // Built-in LED pin on Arduino UNO

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. No Output Voltage:

   • Verify that the input voltage is within the specified range (6V to 24V).
   • Check all connections for proper polarity and secure contact.
   • Ensure the potentiometer is not set to the minimum output voltage.

2. Output Voltage is Unstable:

   • Check if the input power supply is stable and capable of providing sufficient current.
   • Ensure the load does not exceed the maximum output current of 2A.
   • Inspect the module for overheating and provide adequate ventilation if necessary.

3. Module Overheats:

   • Reduce the load current if it exceeds 2A.
   • Use a heatsink or active cooling to dissipate heat during high-current operation.

4. Short Circuit Protection Triggered:

   • Disconnect the load and inspect for short circuits in the connected circuit.
   • Reset the module by removing and reapplying the input power.
