The following table outlines the key technical details of the Módulo 03962A Cargador de batería:

The Módulo 03962A has the following pinout:

1. Connect the Input Voltage:

   • Connect a DC power source (5V to 20V) to the VIN+ and VIN- pins.
   • Ensure the input voltage matches the requirements of the battery being charged.

2. Connect the Battery:

   • Attach the battery's positive terminal to the BAT+ pin and the negative terminal to the BAT- pin.
   • Double-check the polarity to avoid damage to the module or battery.

3. Adjust the Output Voltage:

   • Use the ADJ pin or onboard potentiometer (if available) to set the desired charging voltage.
   • Refer to the battery's datasheet for the correct charging voltage.

4. Monitor Charging Status:

   • Observe the LED1 and LED2 indicators for charging progress:
     • LED1 (red): Charging in progress.
     • LED2 (green): Charging complete.

• Verify Battery Specifications: Ensure the battery's voltage and current ratings are compatible with the module.
• Heat Dissipation: If charging at high currents, ensure proper ventilation or add a heatsink to prevent overheating.
• Avoid Overdischarge: Do not connect deeply discharged batteries, as this may damage the module or the battery.
• Safety First: Always handle batteries with care to avoid short circuits, overheating, or fire hazards.

The Módulo 03962A can be used in conjunction with an Arduino UNO to monitor the charging process. Below is an example code snippet to read the charging status using the Arduino's digital pins:

// Define pins for the charging status LEDs
const int chargingPin = 2;  // Connect LED1 (charging indicator) to pin 2
const int chargedPin = 3;   // Connect LED2 (charged indicator) to pin 3

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);

  // Set the LED pins as input
  pinMode(chargingPin, INPUT);
  pinMode(chargedPin, INPUT);
}

void loop() {
  // Read the status of the charging and charged LEDs
  int chargingStatus = digitalRead(chargingPin);
  int chargedStatus = digitalRead(chargedPin);

  // Print the charging status to the Serial Monitor
  if (chargingStatus == HIGH) {
    Serial.println("Battery is charging...");
  } else if (chargedStatus == HIGH) {
    Serial.println("Battery is fully charged!");
  } else {
    Serial.println("No battery detected or idle state.");
  }

  // Add a small delay to avoid flooding the Serial Monitor
  delay(1000);
}

1. Module Not Powering On:

   • Cause: Incorrect input voltage or loose connections.
   • Solution: Verify the input voltage is within the 5V to 20V range and check all connections.

2. Battery Not Charging:

   • Cause: Incorrect polarity or incompatible battery type.
   • Solution: Double-check the battery's polarity and ensure it matches the module's specifications.

3. Overheating During Operation:

   • Cause: High charging current or poor ventilation.
   • Solution: Reduce the charging current or improve heat dissipation with a heatsink or fan.

4. LED Indicators Not Working:

   • Cause: Faulty LEDs or incorrect wiring.
   • Solution: Test the LEDs with a multimeter and verify the connections.

Q1: Can this module charge multiple batteries in series?
A1: Yes, but ensure the total voltage of the series-connected batteries matches the module's output voltage.

Q2: Is it safe to leave the battery connected after it is fully charged?
A2: Yes, the module includes overcharge protection to prevent damage to the battery.

Q3: Can I use this module with a solar panel?
A3: Yes, as long as the solar panel's output voltage and current are within the module's input range.

Q4: How do I adjust the charging current?
A4: The charging current is typically fixed, but some versions of the module may allow adjustment via a resistor or potentiometer. Check the module's datasheet for details.
