Applications

• Smart Home Hubs: Use it as a lightweight MQTT broker or Home Assistant satellite.
• Portable Retro Gaming: Power a Retropie handheld using the compact form factor.
• Headless Ad-Blocker: Run Pi-hole to protect your entire network from ads.
• Time-Lapse Photography: Connect a Pi Camera via the CSI port for long-term monitoring.

Project Evolution

• Past Projects (Prerequisites): If you’ve already mastered blinking LEDs with an Arduino or ESP32, the Zero W is your entry into the world of Linux-based computing.
• Feature Upgrade: Moving to the Zero W unlocks a full Operating System, allowing you to run Python scripts with advanced libraries, host local web servers, and manage complex file systems.
• Effort/Requirements: Intermediate. Requires a MicroSD card (8GB+), a Mini-HDMI adapter, and basic terminal knowledge for headless setup.

Virtual Technician & Wiring

• ⚠️ Safety Note: This board is Probots Logic-Safe. All GPIO pins operate at 3.3V. Connecting 5V sensors directly to the pins will permanently damage the BCM2835 chip. Always use a level shifter for 5V components.

Package Including :

• 1 X Raspberry Pi Zero W
