• Insufficient Power Supply. Low-quality adapters can cause reboots, so always use a reliable 5V/2.5A power source.

• Limited RAM. With only 1GB of memory, multitasking can slow down, so lightweight OS or optimized apps are recommended.

• SD Card Corruption. Power loss may damage the card, so using quality Class 10 microSDs and backups prevents issues.

• Slow Storage Speed. MicroSD cards can be sluggish, so high-speed cards or USB boot options improve performance.

• Wi-Fi Connectivity Issues. Weak signals may cause dropouts, so positioning near the router or using Ethernet ensures stability.

• Limited Processing Power. Demanding tasks can overwhelm the CPU, so optimized software or upgrading to Pi 4 is better.

• Peripheral Compatibility. Some USB devices may fail, so powered hubs or supported software should be used.
