The Nano 33 BLE (without headers) is Arduino's 3.3V-compatible board in the smallest available form factor! The Arduino Nano 33 BLE is a completely new board on a well-known form factor. It comes with an embedded 9-axis inertial sensor making this board ideal for wearable devices as well as a large range of scientific experiments needing short-distance wireless communication.
The Arduino Nano 33 BLE is an evolution of the traditional Arduino Nano but features a much more powerful processor, the nRF52840 from Nordic Semiconductors which is a 32-bit ARM® Cortex™-M4 CPU running at 64 MHz. This will allow you to make larger programs than with the Arduino Uno (it has 1MB of program memory, 32 times more space), and with a lot more variables (the RAM is 128 times bigger). The main processor includes other amazing features like Bluetooth pairing via NFC and ultra-low power consumption modes.
The embedded 9-axis inertial measurement unit (IMU) means that it has an accelerometer, a gyroscope, and a magnetometer with 3-axis resolution each. This makes the Nano 33 BLE the perfect choice for more advanced robotics experiments, exercise trackers, digital compasses and more!
