Overview
The Breadboard Power Supply (3.3V-5V) is a compact and convenient module designed to provide a stable power supply to breadboard-based projects. It features a compact design, making it easy to integrate into prototype circuits. This documentation provides a detailed explanation of the module's pins and how to connect them.
Pinout Description
The Breadboard Power Supply (3.3V-5V) has a total of 6 pins, labeled as follows:
Pin 1: Vin (Input Voltage)
Function: Input voltage pin, connects to an external power source (e.g., a wall adapter or battery).
Voltage Range: 6.5V - 12V (recommended), 5V - 15V (absolute maximum).
Notes: Be cautious when selecting the input voltage, as exceeding the recommended range may damage the module.
Pin 2: GND (Ground)
Function: Ground pin, provides a common reference point for the module's output voltage.
Notes: Connect to the negative terminal of the input power source and the ground rail on the breadboard.
Pin 3: 5V (Output Voltage)
Function: 5V regulated output voltage pin, suitable for most microcontrollers, sensors, and other 5V devices.
Voltage Tolerance: 5% (i.e., 4.75V - 5.25V).
Current Capacity: Typically up to 500mA, depending on the input voltage and module quality.
Pin 4: 3.3V (Output Voltage)
Function: 3.3V regulated output voltage pin, suitable for devices requiring a lower voltage, such as some microcontrollers, sensors, and low-voltage ICs.
Voltage Tolerance: 5% (i.e., 3.135V - 3.465V).
Current Capacity: Typically up to 500mA, depending on the input voltage and module quality.
Pin 5: EN (Enable)
Function: Enable pin, allows the user to control the power supply's output.
Logic: Active-high, meaning the output is enabled when the EN pin is pulled high (connected to Vin or 5V).
Notes: Leave the EN pin unconnected or tie it to Vin or 5V to enable the power supply by default.
Pin 6: NC (No Connection)
Function: No internal connection, reserved for potential future use or modification.
Notes: Do not connect anything to this pin, as it may cause damage to the module.
Connection Structure
To use the Breadboard Power Supply (3.3V-5V) module, follow this connection structure:
1. Input Power:
Connect the positive terminal of the input power source (e.g., a wall adapter or battery) to Pin 1 (Vin).
Connect the negative terminal of the input power source to Pin 2 (GND).
2. Output Voltages:

Code Examples

### Example 1: Basic Usage with Arduino Uno

In this example, we'll use the Breadboard Power Supply (3.3V-5V) to power an Arduino Uno board. We'll set the output voltage to 5V and connect the power supply to the Arduino's VIN and GND pins.

```c
// No code required, just connect the power supply to the Arduino Uno
// VIN -> Arduino VIN
// GND -> Arduino GND
// VOUT -> 5V pin on the Arduino
```

### Example 2: Using the Enable Pin with Raspberry Pi Pico

In this example, we'll use the Breadboard Power Supply (3.3V-5V) to power a Raspberry Pi Pico board. We'll set the output voltage to 3.3V and connect the power supply to the Raspberry Pi Pico's VBUS and GND pins. We'll also use the enable pin to control the power supply.

```python
import machine

# Define the enable pin as an output
en_pin = machine.Pin(0, machine.Pin.OUT)

# Set the enable pin high to turn on the power supply
en_pin.value(1)

# Wait for the power supply to stabilize
machine.sleep(0.1)

# Connect the power supply to the Raspberry Pi Pico
# VIN -> Raspberry Pi Pico VBUS
# GND -> Raspberry Pi Pico GND
# VOUT -> 3.3V pin on the Raspberry Pi Pico

# To turn off the power supply, set the enable pin low
en_pin.value(0)
```

Tips and Precautions

Make sure to connect the input voltage (VIN) to a suitable power source within the recommended range (6.5V to 12V).
 Always connect the ground pin (GND) to a common ground point in your circuit.
 The enable pin (EN) is active high, meaning the power supply is enabled when the pin is set high (VCC) and disabled when set low (GND).
 Be cautious when handling the Breadboard Power Supply (3.3V-5V) to avoid short circuits and damage to the module or connected devices.
