An improvement on the original Arduino Nano, the Arduino Nano 33 BLE Sense has a much more potent processor—the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex™-M4 CPU operating at 64 MHz. Compared to the Arduino Uno, which has 1MB of program memory, this will enable you to create programs that are 32 times larger and have a lot more variables (the RAM is 128 times larger). Other incredible features of the main processor include ultra low power consumption modes and Bluetooth® pairing via NFC. In addition to its impressive sensor selection, this board's primary feature is its ability to run Edge Computing (AI) applications using TinyML. You can use TensorFlow™ Lite to generate and upload your machine learning models.
