Compact size: 35x20mmPinoutThe module has the following pins:VCC: Input voltage (5V)
GND: Ground
BAT: Battery connection (18650 lithium battery)
CHG: Charging indicator (LED)
DIS: Discharging indicator (LED)
OUT: Output voltage (5V)Example 1: Simple Power BankIn this example, we'll demonstrate how to use the 2in1 charge discharge board module to build a simple power bank.Components1 x 2in1 charge discharge board module
1 x 18650 lithium battery
1 x Micro-USB connector (for charging)
1 x USB-A connector (for discharging)CodeNo code is required for this example, as the module operates independently. Simply connect the Micro-USB connector to a power source (e.g., a wall adapter) to charge the battery. The CHG LED will indicate when the battery is charging. Once the battery is fully charged, the DIS LED will turn on, and the power bank is ready to use.Example 2: Arduino-Based Battery MonitorIn this example, we'll use the 2in1 charge discharge board module with an Arduino board to monitor the battery's state of charge (SoC) and voltage.Components1 x 2in1 charge discharge board module
1 x Arduino board (e.g., Arduino Uno)
1 x 18650 lithium battery
1 x BME280 temperature and humidity sensor (optional)Code
```c++
const int batVoltagePin = A0; // Analog input for battery voltage
const int batSoCPin = A1; // Analog input for battery SoC
const int ledPin = 13; // Digital output for LED indicatorvoid setup() {
pinMode(ledPin, OUTPUT);
pinMode(batVoltagePin, INPUT);
pinMode(batSoCPin, INPUT);
}void loop() {
int batVoltage = analogRead(batVoltagePin);
int batSoC = analogRead(batSoCPin);
// Calculate battery voltage and SoC
float voltage = batVoltage 5.0 / 1023.0;
float soc = map(batSoC, 0, 1023, 0, 100);
// Print battery voltage and SoC to serial monitor
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println("V");
Serial.print("Battery SoC: ");
Serial.print(soc);
Serial.println("%");
// Turn on LED if battery is fully charged
if (soc >= 90) {
digitalWrite(ledPin, HIGH);
} else {
digitalWrite(ledPin, LOW);
}
delay(1000);
}
```
In this example, we use the Arduino board to read the battery voltage and SoC from the analog inputs of the 2in1 charge discharge board module. We then calculate the battery voltage and SoC and print them to the serial monitor. Finally, we use an LED to indicate when the battery is fully charged.Note: This code is for illustration purposes only and may require modifications to work with your specific setup.
