About Raspberry Pi Zero
The Raspberry Pi Zero is an ultra-compact, low-cost single-board computer perfect for embedded projects, wearables, and space-constrained applications. Available variants:
- Pi Zero: Basic model with mini-HDMI, micro-USB (data and power), and unpopulated GPIO header
- Pi Zero W: Adds 2.4GHz WiFi and Bluetooth
- Pi Zero 2 W: Upgraded quad-core processor, WiFi, and Bluetooth
All models share the same compact form factor (65mm × 30mm) and require adapters or soldering for many peripherals.
What you'll need
To get started with your Raspberry Pi Zero:
- Raspberry Pi Zero, Zero W, or Zero 2 W
- MicroSD card (8GB minimum, 16GB or larger recommended) with Raspberry Pi OS installed
- Power supply: 5V micro-USB power adapter (2.5A recommended)
- Mini-HDMI to HDMI adapter or cable for connecting to a monitor
- Micro-USB OTG adapter for connecting USB keyboard and mouse (or USB hub)
- Optional: GPIO header (40-pin, requires soldering or press-fit installation)
Note: Unlike full-size Raspberry Pi boards, the Pi Zero uses mini-HDMI and micro-USB ports, requiring adapters for standard peripherals.
Assembly & connections
- Insert microSD card: Insert the microSD card (with Raspberry Pi OS pre-loaded) into the slot on the underside of the Pi Zero.
- Install GPIO header (optional): If your projects require GPIO access, solder or press-fit a 40-pin GPIO header to the Pi Zero. See our Pi Zero header rig instructions for press-fit installation.
- Connect display: Use a mini-HDMI to HDMI adapter or cable to connect the Pi Zero to your monitor or TV.
- Connect peripherals: Use a micro-USB OTG adapter or hub connected to the Pi Zero's USB port (marked "USB", not "PWR"). Plug in a USB keyboard and mouse (or a USB hub if using multiple devices).
- Connect power: Connect a 5V micro-USB power supply to the port marked "PWR" (the port nearest the HDMI connector). The Pi Zero will boot automatically when power is applied.
Headless setup (no monitor): You can configure the Pi Zero W or Zero 2 W to connect to WiFi and enable SSH before first boot. See the Raspberry Pi documentation for headless WiFi setup.
First boot
On first boot, Raspberry Pi OS will launch the setup wizard (if using the desktop version):
- Initial setup: Follow the on-screen prompts to select your country, language, timezone, and keyboard layout.
- Set password: Create a password for the default user.
- Connect to WiFi: On Pi Zero W or Zero 2 W, select your wireless network and enter the password.
- Update software: Allow the system to check for and install updates (recommended).
If using Raspberry Pi OS Lite (command-line only), you'll be prompted to log in. Default username is pi (or the username you configured during imaging). Run sudo raspi-config to configure WiFi, localization, and other settings.
Next steps
Your Raspberry Pi Zero is ready to use. Here are some ideas to get started:
- Compact projects: The Pi Zero's small size makes it ideal for wearables, camera projects (with Pi Zero Camera Cable), and embedded systems.
- GPIO projects: With a GPIO header installed, try LED control, sensor reading, or HAT accessories designed for Pi Zero.
- Retro gaming: Install RetroPie for a pocket-sized retro gaming console.
- IoT devices: Use the Pi Zero W or Zero 2 W for WiFi-connected sensors, home automation nodes, or data loggers.
Adapters and accessories: Consider purchasing a Pi Zero starter kit that includes essential adapters (mini-HDMI, micro-USB OTG), a case, and GPIO header for easier setup.
