Arduino Nano 33 Ble Sense with Header-Rev 2

The Arduino Nano BLE Sense (Rev-2) is a compact, powerful development board designed for embedded AI, IoT, and sensor-rich applications. It is built around a 32-bit ARM Cortex-M4F microcontroller with Bluetooth Low Energy, and it integrates multiple onboard sensors for motion, environment, sound, color, and proximity sensing. Rev-2 improves sensor accuracy and reliability compared to earlier versions while maintaining the classic Nano form factor for easy breadboard and prototype use.
