Solar Power Manager 5V Pinout Explanation
The Solar Power Manager 5V is a compact and efficient power management module designed for IoT projects, robots, and other battery-powered devices. It features a robust design, high accuracy, and multiple protection mechanisms to ensure safe and reliable power supply. Here's a detailed explanation of the pins:
Pinout Structure:
The Solar Power Manager 5V has a total of 8 pins, arranged in two rows of 4 pins each.
Row 1 (Left to Right):
1. VIN (Input Voltage):
This pin is used to connect the positive terminal of the solar panel or an external power source.
Input voltage range: 6V to 24V
Recommended input voltage: 12V (for optimal performance)
2. VOUT (Output Voltage):
This pin provides a regulated 5V output voltage, suitable for most IoT devices and microcontrollers.
Output voltage: 5V 2%
Maximum output current: 2A
3. GND (Ground):
This pin is the common ground for the module and should be connected to the negative terminal of the solar panel, battery, or other power sources.
Ensure a solid ground connection to prevent any noise or interference issues.
4. EN (Enable Pin):
This pin is used to enable or disable the power output.
Pulling the EN pin high (logic level 1) enables the power output; pulling it low (logic level 0) disables the output.
Row 2 (Left to Right):
1. BAT+ (Battery Positive):
This pin connects to the positive terminal of the rechargeable battery.
The module will charge the battery when the input voltage is present and the battery is not fully charged.
2. BAT- (Battery Negative):
This pin connects to the negative terminal of the rechargeable battery.
Ensure a solid connection to the battery negative terminal to prevent any issues during charging and discharging.
3. CHARGE (Charge Indicator):
This pin provides a logic-level output that indicates the charging status of the battery.
When the battery is charging, this pin will be high (logic level 1); when the battery is fully charged or not charging, it will be low (logic level 0).
4. FAULT (Fault Indicator):
This pin provides a logic-level output that indicates any faults or errors in the power management system.
When a fault occurs, this pin will be high (logic level 1); otherwise, it will be low (logic level 0).
Connection Structure:
Here's a general connection structure for the Solar Power Manager 5V:
Connect the solar panel or external power source to VIN and GND.
Connect the rechargeable battery to BAT+ and BAT-.
Connect the 5V output devices (e.g., microcontrollers, sensors, or other IoT components) to VOUT and GND.
Use the EN pin to control the power output if necessary.
Monitor the CHARGE and FAULT pins for charging status and fault detection.
Important Notes:
Always follow proper safety precautions when working with electrical components and power sources.
Ensure the input voltage and current ratings of the module are not exceeded.
Use a suitable rechargeable battery with a compatible charging profile.
Refer to the datasheet and manufacturer's instructions for specific details and recommendations.
By following this pinout explanation and connection structure, you can successfully integrate the Solar Power Manager 5V into your IoT projects and ensure a reliable power supply.

Code Examples

### Example 1: Powering an Arduino Board with Solar Power

In this example, we'll demonstrate how to use the Solar Power Manager 5V to power an Arduino board using a solar panel and a rechargeable battery.

```c
// Assume the Solar Power Manager 5V is connected to the Arduino board
// as follows:
// VIN -> Solar panel
// VBAT -> Rechargeable battery
// VOUT -> Arduino board (5V pin)
// GND -> Arduino board (GND pin)
// EN -> Digital pin 2 (active high)

void setup() {
  pinMode(2, OUTPUT); // Set enable pin as output
  digitalWrite(2, HIGH); // Enable the Solar Power Manager
}

void loop() {
  // Your Arduino code here
  // The Arduino board will receive power from the solar panel
  // through the Solar Power Manager 5V
}
```

### Example 2: Monitoring Solar Power and Battery Status using a MicroPython Board

In this example, we'll demonstrate how to use the Solar Power Manager 5V with a MicroPython board to monitor the solar power and battery status.

```python
import machine

# Assume the Solar Power Manager 5V is connected to the MicroPython board
# as follows:
# VIN -> Solar panel
# VBAT -> Rechargeable battery
# VOUT -> MicroPython board (5V pin)
# GND -> MicroPython board (GND pin)
# EN -> Digital pin 2 (active high)

# Initialize the enable pin as output
enable_pin = machine.Pin(2, machine.Pin.OUT)
enable_pin.value(1)  # Enable the Solar Power Manager

# Define the ADC pins for solar power and battery voltage monitoring
solar_adc = machine.ADC(0)  # VIN pin
battery_adc = machine.ADC(1)  # VBAT pin

while True:
    # Read solar power voltage
    solar_voltage = solar_adc.read_u16()  3.3 / 65535
    print("Solar power voltage: ", solar_voltage, "V")

# Read battery voltage
    battery_voltage = battery_adc.read_u16()  3.3 / 65535
    print("Battery voltage: ", battery_voltage, "V")

# Add your logic to handle the monitored values
    # ...
```

Note: In both examples, ensure proper wiring and connections are made according to the component's datasheet and the specific board or device being used.
