The Arduino Nano 33 BLE Rev2 is a significant leap forward in the world of microcontroller boards, designed to empower a diverse array of projects with its advanced capabilities.

Arduino has bought out second revisions of its Nano 33 BLE and Nano 33 BLE Sense bluetooth-equipped microcontroller boards, keeping the sensor mix, but changing several of the sensor ICs.

While the Arduino Nano 33 BLE Sense offers a small, powerful, BT connected development board with all the sensors you may need to design innovative applications.

Getting started with BLE is easier than ever. T.K. Hareendran uses an inexpensive Texas Instruments CC2541 based module, Arduino, and Android to get connected.

The “Nano 33 BLE” and “Nano 33 BLE Sense” boards both do away with the SAMD21 chip and utilize the Nordic nRF52480 which is part of the uBlox NINA-B306 modules and provide Bluetooth ...

This example of a Bluetooth-controlled car created with an Arduino UNO, a 25-gram board, can be dropped to seven grams with a Nano and even lower to five with a Nano Every in its place.

In Connecting to Intel® Edison from Android* with Bluetooth* LE (BLE) describes a way to access BT via Arduino code but additional BT shield/kit is required.

Arduino has announced four new Nano microcontroller-based boards that will be available for developers and makers in late July.
