Raspberry Pi Zero 2 W with Headers Documentation
Overview
The Raspberry Pi Zero 2 W with Headers is a compact, low-cost, and highly capable single-board computer (SBC) designed for IoT, robotics, and embedded systems applications. This version comes with pre-soldered headers, making it easy to connect peripherals and sensors. The Raspberry Pi Zero 2 W is built around the Broadcom BCM2710A1 system-on-chip (SoC), which features a quad-core Cortex-A53 CPU, dual-band 802.11b/g/n wireless networking, and Bluetooth 4.2.

Operating System: Raspberry Pi OS (based on Linux)
Code Examples
### Example 1: GPIO Control using Python
In this example, we will use the Raspberry Pi Zero 2 W to control an LED connected to one of the GPIO pins.
Hardware Requirements
Raspberry Pi Zero 2 W with Headers
Breadboard
LED
1 k resistor
Jumper wires
Software Requirements
Raspberry Pi OS (latest version)
Python 3.x
Code
```python
import RPi.GPIO as GPIO
import time
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Set up pin 17 as an output
GPIO.setup(17, GPIO.OUT)
try:
while True:
# Turn on the LED
GPIO.output(17, GPIO.HIGH)
time.sleep(1)
# Turn off the LED
GPIO.output(17, GPIO.LOW)
time.sleep(1)
except KeyboardInterrupt:
# Clean up GPIO on exit
GPIO.cleanup()
```
Explanation
This code uses the RPi.GPIO library to control the GPIO pin 17, which is connected to the LED. The `GPIO.setmode(GPIO.BCM)` function sets the GPIO mode to Broadcom numbering. The `GPIO.setup(17, GPIO.OUT)` function sets pin 17 as an output. The `GPIO.output(17, GPIO.HIGH)` and `GPIO.output(17, GPIO.LOW)` functions turn the LED on and off, respectively. The `time.sleep(1)` function introduces a 1-second delay between each state change.
### Example 2: Wi-Fi Connectivity using Python
In this example, we will use the Raspberry Pi Zero 2 W to connect to a Wi-Fi network and retrieve a web page using Python.
Hardware Requirements
Raspberry Pi Zero 2 W with Headers
Wi-Fi network
Internet connection
Software Requirements
Raspberry Pi OS (latest version)
Python 3.x
`requests` library (install using `pip install requests`)
Code
```python
import requests
# Set up Wi-Fi connection
ssid = 'your_wifi_ssid'
password = 'your_wifi_password'
# Connect to Wi-Fi
print('Connecting to Wi-Fi...')
import subprocess
subprocess.run(['sudo', 'iwconfig', 'wlan0', 'essid', ssid])
subprocess.run(['sudo', 'iwconfig', 'wlan0', 'key', password])
# Check Wi-Fi connection
print('Checking Wi-Fi connection...')
import subprocess
result = subprocess.run(['sudo', 'iwconfig', 'wlan0', 'link'])
if result.returncode == 0:
print('Wi-Fi connected!')
# Retrieve a web page
print('Retrieving a web page...')
response = requests.get('https://www.example.com')
print(response.text)
```
Explanation
This code uses the `requests` library to connect to a Wi-Fi network and retrieve a web page. The `subprocess` module is used to run shell commands to configure the Wi-Fi interface. The `iwconfig` command is used to set the Wi-Fi SSID and password. The `link` command is used to check the Wi-Fi connection status. Finally, the `requests.get()` function is used to retrieve the web page.
Note: Replace `your_wifi_ssid` and `your_wifi_password` with your actual Wi-Fi credentials.
These examples demonstrate the versatility and ease of use of the Raspberry Pi Zero 2 W with Headers in various IoT applications.
