Exceptional/ 10
“The Raspberry Pi 4 is the ultimate IoT brain. When your project needs real computing power with Linux, nothing beats the Pi's ecosystem and community.”
- Powerful quad-core with 4GB RAM runs full Linux
- Dual-band WiFi, BLE, and Gigabit Ethernet connectivity
- Massive ecosystem of HATs, cases, and software
- No built-in analog inputs — needs external ADC
- microSD storage is slow and prone to corruption
- Overkill for simple sensor-reading tasks
