Buying advice

Consider your project requirements: processing power, connectivity (WiFi/Bluetooth), size, and community support. For beginners, Arduino Uno offers the best learning resources. For IoT, ESP32 provides built-in wireless. Raspberry Pi is best for complex tasks needing a full OS. Always verify authenticity from trusted sellers to avoid counterfeit boards.
