| Pin Name | Description |
|---|---|
| IN+ | Positive input terminal for the solar panel (4.4V to 6V input range). |
| IN- | Negative input terminal for the solar panel (ground). |
| BAT+ | Positive terminal for the lithium-ion battery. |
| BAT- | Negative terminal for the lithium-ion battery (ground). |
| STAT | Status indicator pin (low when charging, high when fully charged). |
Connect the Solar Panel:
IN+ pin.IN- pin.Connect the Lithium-ion Battery:
BAT+ pin.BAT- pin.Monitor Charging Status:
STAT pin to monitor the charging status.
STAT pin will output a low signal.STAT pin will output a high signal.Power Considerations:
The CN3065 can be used to power an Arduino UNO by charging a lithium-ion battery, which then supplies power to the Arduino. Below is an example of how to monitor the charging status using the STAT pin:
// Example code to monitor CN3065 charging status with Arduino UNO
const int statPin = 2; // Connect the STAT pin of CN3065 to digital pin 2
void setup() {
pinMode(statPin, INPUT); // Set STAT pin as input
Serial.begin(9600); // Initialize serial communication
}
void loop() {
int chargingStatus = digitalRead(statPin); // Read the STAT pin state
if (chargingStatus == LOW) {
// STAT pin is LOW when the battery is charging
Serial.println("Battery is charging...");
} else {
// STAT pin is HIGH when the battery is fully charged
Serial.println("Battery is fully charged!");
}
delay(1000); // Wait for 1 second before checking again
}
Module Not Charging the Battery:
Battery Overheating:
STAT Pin Not Responding:
STAT pin is properly connected to the monitoring device.Low Charging Efficiency:
Q1: Can I use this module with a 6V lead-acid battery?
A1: No, the CN3065 is designed specifically for single-cell lithium-ion batteries with a nominal voltage of 3.7V.
Q2: What happens if the input voltage exceeds 6V?
A2: Input voltages above 6V can damage the module. Always use a solar panel within the specified voltage range.
Q3: Can I connect a load directly to the battery while charging?
A3: It is not recommended, as it may overload the module and reduce charging efficiency.
Q4: How do I know if the module is working correctly?
A4: Monitor the STAT pin or check the battery voltage to ensure it is charging properly.
