Arduino Nano 33 BLE Sense Rev2 with Headers (ABX00070) – AI-Enabled IoT Development Board with Bluetooth 5.0 & Built-in Sensors
The Arduino Nano 33 BLE Sense Rev2 is Arduino's most advanced compact development board, purpose-built for AI at the edge, IoT sensing, and wearable applications. At its core sits the powerful Nordic nRF52840 microcontroller featuring a 32-bit Arm Cortex-M4F processor clocked at 64 MHz with 1 MB of Flash and 256 KB of SRAM — giving you ample headroom for TinyML models using TensorFlow Lite Micro. What sets this board apart is its rich suite of onboard environmental sensors: a 9-axis IMU (BMI270 accelerometer + gyroscope, BMM150 magnetometer), the MP34DT05 digital MEMS microphone for voice and audio capture, a LPS22HB barometric pressure sensor, and the HTS221 capacitive temperature and humidity sensor. All sensors communicate over I2C, keeping your digital pins free for other peripherals. Bluetooth 5.0 and BLE connectivity are handled by the onboard NINA B306 module, making wireless data streaming, beaconing, and mesh networking straightforward. The board operates at 3.3V logic but can accept up to 21V on the VIN pin thanks to its robust onboard regulator. With 14 digital I/O pins, 8 analog inputs (12-bit ADC), UART, SPI, and I2C interfaces, this board slots into the Arduino ecosystem seamlessly. Whether you are a student building a smart weather station, an engineer prototyping an industrial predictive maintenance sensor, or a researcher experimenting with on-device machine learning, the Nano 33 BLE Sense Rev2 gives you a production-grade sensing platform in a tiny 45×18 mm footprint. This listing is for the ABX00070 variant with pre-soldered male headers, ready to plug into a breadboard right out of the box. Fully supported in the Arduino IDE 2.x, PlatformIO, and MicroPython, with extensive open-source libraries for every onboard sensor.

Details
Looking for a tiny yet powerful AI-enabled Arduino board with built-in sensors? The Arduino Nano 33 BLE Sense Rev2 is a game-changer for IoT, wearable tech, and TinyML projects in India. Unlike older Arduino boards that need external sensor breakouts, this Rev2 packs a 9-axis IMU, digital microphone, barometric pressure sensor, and temperature/humidity sensor right on the PCB — all in a 45×18 mm footprint that fits on any breadboard.
The heart of the board is the Nordic nRF52840 SoC, a 32-bit Arm Cortex-M4F running at 64 MHz with 1 MB Flash and 256 KB SRAM. This is the same silicon used in professional BLE products, and it supports Bluetooth 5.0 with long-range and high-throughput modes. The onboard NINA B306 module handles the radio stack, freeing the main MCU for your application logic. For AI and machine learning enthusiasts, this board is fully compatible with TensorFlow Lite Micro and Edge Impulse, letting you deploy on-device inference for keyword spotting, gesture recognition, vibration analysis, and more — without a cloud connection.
Each sensor is a best-in-class industrial part: the BMI270 provides 6-axis motion sensing with hardware sensor fusion, the BMM150 extends that to 9-axis compass heading, the MP34DT05 MEMS microphone captures clear audio up to 16-bit resolution ideal for voice commands, the LPS22HB measures atmospheric pressure with ±0.1 hPa accuracy, and the HTS221 delivers temperature (±0.5°C) and humidity (±3.5% RH) readings over I2C. All of these have dedicated Arduino libraries maintained by the official sensor manufacturers (Bosch Sensortec, STMicroelectronics), so you can start reading sensor data in fewer than 10 lines of code.
For Indian engineering students and makers, this board is a one-stop solution for final-year projects like IoT weather stations, air quality monitors, voice-controlled home automation, fall detectors, drone altimeters, and predictive maintenance. It is also a favourite in hackathons and research labs because you get six sensors and Bluetooth LE on a single board — no messy jumper wires, no soldering, just plug it into USB and start coding. The ABX00070 variant comes with headers pre-soldered, saving you time and ensuring reliable breadboard connections. It works out of the box with Arduino IDE 2.x, PlatformIO, and even MicroPython via the OpenMV firmware. If you are building the future of smart devices in India, the Nano 33 BLE Sense Rev2 is your Swiss Army knife.
