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 . Its miniature footprint, approximately the size of a stick of gum, makes it ideal for embedded applications .
UltraCompact Design Fits into space-constrained projects
Runs Full Operating System Supports Raspberry Pi OS and Linuxbased applications
Requires a microSD card with Raspberry Pi OS installed, 5V micro USB power supply, and mini HDMI cable for display
Uses a micro USB OTG port for connecting peripherals like keyboards and mouse
The 40-pin GPIO header is unpopulated and typically requires soldering for use

= Troubleshooting =
No video output:
- Ensure microSD card has properly installed Raspberry Pi OS
- Use a mini HDMI to HDMI adapter or cable
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
- Confirm using 2.4GHz network (not 5GHz)
