About this item

The Official Arduino Nano 33 BLE (Without Header) is a compact, 3.3V microcontroller board designed for developers seeking low-power wireless connectivity in a small form factor. Measuring only 45x18mm, it’s one of the smallest Arduino boards, ideal for space-constrained projects. Powered by the nRF52840 from Nordic Semiconductors—a 32-bit ARM Cortex-M4 processor running at 64 MHz—this board offers improved performance, enhanced memory, and reliable wireless communication.An upgrade from the classic Arduino Nano, the Nano 33 BLE integrates Bluetooth Low Energy (BLE) and supports secure IoT communication. Its ultra-low power consumption makes it suitable for wearable devices, remote sensors, and battery-powered projects. While this version comes without pre-soldered headers, it offers flexibility for custom hardware integration.Fully compatible with the Arduino ecosystem, the board provides an easy development experience, whether you're building connected prototypes or exploring Bluetooth applications. Its robust BLE support allows for fast and secure data exchange, while the 3.3V logic level ensures compatibility with modern low-power peripherals. Whether you're designing smart gadgets, wireless sensors, or BLE-enabled devices, the Nano 33 BLE offers power and flexibility in a tiny, affordable package.
