41. BOOT_SEL (Pin 41): Boot select pin, used for boot mode selection.
Note: The Raspberry Pi Pico W has a 40-pin GPIO header, but some pins are duplicated or have multiple functions. Be sure to consult the official documentation and datasheets for specific pin configurations and usage guidelines.
Connecting Pins: A Step-by-Step Guide
When connecting pins on the Raspberry Pi Pico W, follow these steps:
1. Identify the pin: Determine the pin you want to use, and its function (e.g., GPIO, ADC, power, etc.).
2. Choose the correct jumper wire: Select a suitable jumper wire or connector that matches the pin's voltage rating and signal type (e.g., digital, analog, or power).
3. Connect the jumper wire: Gently insert the jumper wire into the desired pin on the Raspberry Pi Pico W. Make sure it's securely seated and won't come loose over time.
4. Connect the peripheral or device: Attach the other end of the jumper wire to the corresponding pin on the peripheral or device you're connecting (e.g., sensor, LED, buzzer, etc.).
5. Double-check connections: Verify that all connections are secure, correct, and meet the voltage and signal requirements.
6. Test your setup: Power on the Raspberry Pi Pico W and test your project to ensure it's functioning as expected.
Remember to handle the board and components with care, and follow proper electrostatic discharge (ESD) precautions to avoid damaging your Raspberry Pi Pico W or connected devices.

Examples and Code Snippets

Example 1: Wi-Fi Connectivity and HTTP Request

In this example, we will demonstrate how to connect the Raspberry Pi Pico W to a Wi-Fi network and send an HTTP request using the MicroPython firmware.

Code:
```python
import network
import urequests

# Initialize Wi-Fi
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('your_wifi_ssid', 'your_wifi_password')

# Wait for Wi-Fi connection
while not wlan.isconnected():
    pass

print('Connected to Wi-Fi')

# Send HTTP request
response = urequests.get('https://www.example.com')

print(response.text)
```
Example 2: GPIO Control and LED Blinking

In this example, we will show how to control the GPIO pins on the Raspberry Pi Pico W to blink an LED connected to GP15.

Code:
```python
import machine
import time

# Set up GPIO 15 as an output
led = machine.Pin(15, machine.Pin.OUT)

while True:
    # Set LED high (on)
    led.value(1)
    time.sleep(0.5)

# Set LED low (off)
    led.value(0)
    time.sleep(0.5)
```
Example 3: Reading Ambient Temperature with a DS18B20 Sensor

In this example, we will demonstrate how to read the ambient temperature using a DS18B20 sensor connected to the Raspberry Pi Pico W.

Code:
```python
import machine
import onewire

# Initialize OneWire bus on GP16
ow = onewire.OneWire(machine.Pin(16))

# Find the first DS18B20 sensor
sensor = ow.find_first.Device('28.')

while True:
    # Read temperature
    temp = sensor.read_temperature()
    print(f'Temperature: {temp}C')
    time.sleep(1)
```
Note: Make sure to install the required libraries and modules for each example, and adjust the code according to your specific project requirements.
