Description
Raspberry Pi Zero Development Board (Zero / Zero W / Zero WH)
The Raspberry Pi Zero Development Board series is a compact, low-cost single-board computer designed for embedded systems, IoT projects, robotics, and DIY electronics. Despite its small size, it offers powerful computing capabilities suitable for a wide range of maker and industrial applications.
The series includes three main variants:
- Zero – Basic version without wireless connectivity
- Zero W – Adds built-in WiFi and Bluetooth
- Zero WH – Same as Zero W with pre-soldered GPIO header
All variants feature a 1GHz single-core processor with 512MB RAM, making them suitable for lightweight computing, automation, and control applications.
With support for Linux-based operating systems, camera interface, GPIO expansion, and USB OTG functionality, the Raspberry Pi Zero is widely used by makers and developers.
Key Features
- Ultra-compact size (approx. 65 × 30 mm)
- 1GHz single-core processor with 512MB RAM
- Mini HDMI for display output
- Micro USB (power + OTG)
- CSI camera connector
- 40-pin GPIO support
- Linux OS support (Raspberry Pi OS, etc.)
Variants – Comparison
| Variant | Wireless Connectivity | GPIO Header | Best For |
|---|---|---|---|
| Zero | No | Not soldered | Basic embedded projects |
| Zero W | WiFi + Bluetooth | Not soldered | IoT and wireless projects |
| Zero WH | WiFi + Bluetooth | Pre-soldered | Plug-and-play prototyping |
- The Zero W adds onboard WiFi (802.11n) and Bluetooth, making it ideal for wireless applications.
- The Zero WH is essentially a Zero W with pre-soldered GPIO pins, simplifying hardware integration.
