Usage Instructions
How to Use the Charging Module in a Circuit
Power Input: Connect a 5V DC power source to the USB Type-C input connector. This can be a USB adapter, power bank, or any 5V DC source.
Battery Connection:
Connect the positive terminal of the battery to the BAT+ pin.
Connect the negative terminal of the battery to the BAT- pin.
Load Connection (Optional):
If you want to power a load while charging the battery, connect the load's positive terminal to OUT+ and the negative terminal to OUT-.
Adjusting Charging Current:
The default charging current is 1A. To adjust it, connect a resistor to the PROG pin. Refer to the module's datasheet for the resistor value corresponding to the desired current.
Status Indicators:
Connect LEDs to the STAT1 and STAT2 pins to monitor the charging status. Typically, one LED indicates charging, and the other indicates a fully charged battery.
Important Considerations and Best Practices
Ensure the input voltage is stable and within the specified range (5V DC).
Use appropriate wiring and connectors to handle the charging current without overheating.
Avoid short-circuiting the BAT+ and BAT- terminals.
Do not exceed the recommended charging current for your battery to prevent damage.
Place the module in a well-ventilated area to prevent overheating during operation.
Example: Using the Charging Module with an Arduino UNO
The Charging Module can be used to power an Arduino UNO while charging a battery. Below is an example circuit and code:
Circuit Connections
Connect the OUT+ and OUT- pins of the Charging Module to the Arduino UNO's VIN and GND pins, respectively.
Connect a 3.7V lithium-ion battery to the BAT+ and BAT- pins of the module.
Power the module using a USB Type-C cable connected to a 5V DC source.
Example Code
// Example code to monitor battery voltage using Arduino UNO
// Connect the battery's positive terminal to an analog pin (e.g., A0)
const int batteryPin = A0; // Analog pin connected to battery positive terminal
float batteryVoltage = 0.0;
void setup() {
Serial.begin(9600); // Initialize serial communication
pinMode(batteryPin, INPUT); // Set the battery pin as input
}
void loop() {
int sensorValue = analogRead(batteryPin); // Read the analog value
// Convert the analog value to voltage (assuming a 5V reference and 10-bit ADC)
batteryVoltage = sensorValue * (5.0 / 1023.0) * 2;
// Multiply by 2 if a voltage divider is used to measure higher voltages
Serial.print("Battery Voltage: ");
Serial.print(batteryVoltage);
Serial.println(" V");
delay(1000); // Wait for 1 second before the next reading
}
Troubleshooting and FAQs
Common Issues and Solutions
Module Overheating:
