B3 Pro - Li-Po Battery Charger DocumentationOverviewThe B3 Pro Li-Po Battery Charger is a compact and efficient charging module designed for Lithium-Polymer (Li-Po) batteries. It features a high-power charging capacity, overcharge protection, and short-circuit prevention, making it an ideal component for IoT projects and devices.FeaturesHigh-power charging: up to 3A
Overcharge protection: prevents battery damage from overcharging
Short-circuit prevention: protects against short circuits
Compact design: ideal for IoT projects and devices
Wide input voltage range: 4.5V to 24V
Output voltage: 4.2V (fixed)
Output current: up to 3APinoutThe B3 Pro Li-Po Battery Charger has the following pinout:VCC: Input voltage (4.5V to 24V)
GND: Ground
C+: Battery positive terminal
C-: Battery negative terminal
STBY: Standby pin (optional)Code Examples### Example 1: Basic Charging Circuit (Arduino)In this example, we will use the B3 Pro Li-Po Battery Charger with an Arduino board to charge a Li-Po battery.```c++
// Define the pins for the B3 Pro charger
#define Charger_VCC A0 // Input voltage pin
#define Charger_GND GND // Ground pin
#define Charger_CPLUS 2 // Battery positive terminal
#define Charger_CMINUS 3 // Battery negative terminalvoid setup() {
// Initialize the charger pins
pinMode(Charger_VCC, OUTPUT);
pinMode(Charger_GND, OUTPUT);
pinMode(Charger_CPLUS, OUTPUT);
pinMode(Charger_CMINUS, OUTPUT);
// Set the input voltage to 5V
analogWrite(Charger_VCC, 255);
// Connect the battery to the charger
digitalWrite(Charger_CPLUS, HIGH);
digitalWrite(Charger_CMINUS, LOW);
}void loop() {
// The charger will automatically start charging the battery
// No additional code is required
}
```### Example 2: Charging a Li-Po Battery with a MicroPython (Raspberry Pi Pico)In this example, we will use the B3 Pro Li-Po Battery Charger with a Raspberry Pi Pico board to charge a Li-Po battery.```python
import machine# Define the pins for the B3 Pro charger
charger_vcc = machine.Pin(17, machine.Pin.OUT) # Input voltage pin
charger_gnd = machine.Pin(16, machine.Pin.OUT) # Ground pin
charger_cplus = machine.Pin(18, machine.Pin.OUT) # Battery positive terminal
charger_cminus = machine.Pin(19, machine.Pin.OUT) # Battery negative terminal# Set the input voltage to 5V
charger_vcc.value(1)# Connect the battery to the charger
charger_cplus.value(1)
charger_cminus.value(0)# The charger will automatically start charging the battery
# No additional code is required
```Note: In both examples, the input voltage to the charger should be provided from a suitable power source, such as a USB port or a wall adapter. The charger will automatically start charging the Li-Po battery when the input voltage is applied.
