Raspberry Pi Zero W (with Headers) — Tiny Wi‑Fi Linux Computer Ready for GPIO

The Raspberry Pi Zero W (with headers) shrinks a full Linux‑capable Raspberry Pi down to a slim, low‑power board with built‑in Wi‑Fi and Bluetooth. This variant includes a pre‑soldered 40‑pin GPIO header, so you can plug directly into HATs, jumper wires, and shields without touching a soldering iron.

Use it as a compact IoT gateway, mini dashboard, or embedded controller inside custom enclosures. The ready‑made header makes it quick to prototype circuits on a breadboard and then move to a more permanent setup later.

Why this version is convenient

• Tiny form factor: Only about 65 mm × 30 mm, ideal for portable, wearable, or hidden‑mount projects.
• Wireless on board: 2.4 GHz Wi‑Fi and Bluetooth handle connectivity to the cloud, laptops, or phones.
• Pre‑soldered GPIO: 40‑pin header already installed—no soldering required for most tutorials and HATs.
• Low power draw: Much lower consumption than full‑size Pi models, perfect for USB or battery‑powered applications.

Project ideas and applications

• Headless IoT nodes: Run lightweight services, MQTT clients, or data collectors in the background.
• Portable network tools: Build a pocket‑sized Pi‑hole, VPN gateway, or penetration testing toolkit.
• Mini media players: Create compact media boxes or retro gaming handhelds with a tiny HDMI screen.
• Classroom Linux demos: Teach Python, GPIO basics, and networking on a small but capable platform.

Starter bundles

• Zero W GPIO starter: Board + 5 V power supply + microSD card + breadboard + jumper wires.
• Dashboard kit: Add a small HDMI or SPI display, keyboard, mouse, and case.
• Camera kit: Zero W + Raspberry Pi camera + flex cable + mounting accessories.

Recommended add‑ons

• 5 V micro‑USB power supply (around 2 A recommended).
• 8–32 GB microSD card with Raspberry Pi OS Lite or other suitable images.
• Mini HDMI to HDMI cable and USB OTG adapter for USB peripherals.
• Zero W case or custom 3D‑printed mount from Circuitrocks.

Technical specifications

Pinout & power notes

• 3.3 V GPIO: Never drive the pins with 5 V; use level shifters when needed.
• USB power only: Use a stable 5 V supply; avoid low‑quality chargers that sag under load.
• Wireless performance: Keep the antenna end of the board away from metal walls or dense wiring.

What’s in the box

• 1 × Raspberry Pi Zero W board with pre‑soldered 40‑pin GPIO header

FAQ

Is this the same as the Zero W without headers?

Functionally yes. The main difference is that this version already has the 40‑pin GPIO header soldered, which saves time and makes it breadboard‑ready.

Can I power it from a power bank?

Yes, most 5 V USB power banks work well as long as they can supply enough current for the board and accessories.

What operating system should I install?

Raspberry Pi OS Lite is ideal for headless IoT and console‑only use; the full desktop version works for light GUI tasks and development.
