The Big Three
Arduino, Raspberry Pi, and ESP32 dominate the maker world. Each has strengths and limitations — let us break them down.
Arduino
Best for: Simple automation, sensor reading, learning electronics basics. No built-in WiFi. Very affordable.
Raspberry Pi
Best for: Full Linux-based projects, AI on the edge, media centers, complex logic. Has WiFi, Bluetooth, and can run Python natively.
ESP32
Best for: Wireless IoT projects. Built-in WiFi and Bluetooth, dual-core, very cheap. Perfect sweet spot for most IoT projects.
Quick Comparison Table
- Price: Arduino (low) < ESP32 (low) < Raspberry Pi (medium)
- WiFi: Arduino (no) | ESP32 (yes) | Raspberry Pi (yes)
- OS: Arduino (none) | ESP32 (none/RTOS) | Raspberry Pi (Linux)
Our Recommendation
For IoT beginners — start with ESP32. It is the best balance of price, power, and connectivity.
