Raspberry Pi Zero Single-Board Computer
Ultra-Compact Linux Computer for IoT and Embedded Projects
The Raspberry Pi Zero is an ultracompact, lowcost single-board computer designed for projects where space is limited, such as drones, robots, and handheld devices [citation:1]. Its miniature footprint, approximately the size of a stick of gum, makes it ideal for embedded applications [citation:1].
UltraCompact Design Fits into space-constrained projects
Runs Full Operating System Supports Raspberry Pi OS and Linuxbased applications [citation:1]
Requires a microSD card with Raspberry Pi OS installed, 5V micro USB power supply, and mini HDMI cable for display [citation:2]
Uses a micro USB OTG port for connecting peripherals like keyboards and mouse [citation:3]
The 40-pin GPIO header is unpopulated and typically requires soldering for use [citation:3]

Troubleshooting
No video output:
- Ensure microSD card has properly installed Raspberry Pi OS
- Use a mini HDMI to HDMI adapter or cable [citation:2]
Board not booting:
- Check the microSD card is properly inserted and has a valid OS image
- Verify power supply provides 5V and adequate current
Wi-Fi not available (Zero W model):
- Ensure country code is set in Raspberry Pi OS configuration [citation:2]
- Confirm using 2.4GHz network (not 5GHz) [citation:3]
