How to Use Charging nad Booster Module: Examples, Pinouts, and Specs

The Charging and Booster Module is a versatile electronic component designed to charge batteries and boost voltage to a desired level. This module is commonly used in portable electronic projects, such as DIY power banks, portable speakers, and other battery-powered devices. It combines the functionality of a battery charger and a DC-DC boost converter, making it an essential component for projects requiring stable and adjustable power supply.

1. Power Input:

   • Connect the power source (e.g., USB, solar panel) to the IN+ and IN- pins.
   • Ensure the input voltage is within the specified range (3.7V - 5V).

2. Battery Connection:

   • Connect the battery to the B+ and B- pins.
   • Ensure the battery is compatible with the module's charging specifications.

3. Output Connection:

   • Connect the load (e.g., microcontroller, sensors) to the OUT+ and OUT- pins.
   • Adjust the output voltage if necessary using the onboard potentiometer.

• Heat Dissipation: Ensure proper ventilation and heat dissipation, especially when operating at high currents.
• Polarity: Double-check the polarity of all connections to avoid damaging the module.
• Battery Safety: Use batteries with built-in protection circuits to prevent overcharging and over-discharging.
• Load Requirements: Ensure the load does not exceed the maximum output current of the module.

1. Module Not Powering On:

   • Solution: Check the input voltage and ensure it is within the specified range. Verify all connections are secure and correct.

2. Battery Not Charging:

   • Solution: Ensure the battery is properly connected to the B+ and B- pins. Check if the battery is compatible with the module's charging specifications.

3. Output Voltage Not Stable:

   • Solution: Adjust the output voltage using the onboard potentiometer. Ensure the load does not exceed the maximum output current.

4. Module Overheating:

   • Solution: Improve ventilation and heat dissipation. Reduce the load current if necessary.

Q1: Can I use this module with an Arduino UNO?

• A1: Yes, you can use this module to power an Arduino UNO. Connect the OUT+ and OUT- pins to the Arduino's 5V and GND pins, respectively.

Q2: How do I adjust the output voltage?

• A2: Use the onboard potentiometer to adjust the output voltage. Turn the potentiometer clockwise to increase the voltage and counterclockwise to decrease it.

Q3: What type of batteries can I use with this module?

• A3: You can use lithium-ion or lithium-polymer batteries that are compatible with the module's charging specifications.

// Example code to read voltage from the Charging and Booster Module
// and display it on the Serial Monitor

const int voltagePin = A0; // Analog pin to read voltage

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

void loop() {
  int sensorValue = analogRead(voltagePin); // Read the analog input
  float voltage = sensorValue * (5.0 / 1023.0); // Convert to voltage
  Serial.print("Voltage: ");
  Serial.print(voltage);
  Serial.println(" V");
  delay(1000); // Wait for 1 second before next reading
}

This example code reads the voltage from the Charging and Booster Module and displays it on the Serial Monitor. Connect the OUT+ pin to the Arduino's A0 pin and the OUT- pin to the Arduino's GND pin.

By following this documentation, users can effectively integrate the Charging and Booster Module into their projects, ensuring reliable and adjustable power supply for various applications.
